🟣 Geometric Earring Pendant Silicone Mold

I picked this geometric earring mold because I’ve been diving into DIY resin jewelry lately and wanted to make something trendy but minimalistic. The mold looked sharp, with interesting shapes like hexagons and diamonds, and the reviews were strong.

Delivery was faster than expected — about 11 days to the Midwest. It came in a padded envelope and was completely intact, no smell, no warping.

Using it was surprisingly smooth. I poured UV resin into several shapes with glitter and dried flowers. Demolding was super easy, and the edges came out crisp. The depth is great — not too thin, which helps them hold shape without being bulky. Even beginner pours looked decent.

Pros:

  • Easy to use and demold

  • Strong, flexible silicone

  • Great shape variety

  • Perfect for earrings or charms

Cons:

  • No hole guides for jump rings

  • Some shapes are really tiny (easy to overfill)

Compared to US molds on Etsy or Amazon (~$9–12), this one at under $3 was a steal. It absolutely exceeded my expectations, and it’s now one of my favorite molds for making small-batch earring sets.

US $2.39

🟣 Alphabet Resin Mold – Letters and Numbers

I grabbed this alphabet resin mold to personalize keychains and gifts. I liked the clean font style and the inclusion of both uppercase letters and numbers.

Shipping took about two weeks, but tracking was reliable. It arrived flat and dust-free, which isn’t always the case with budget molds.

I tested it with epoxy resin and mica powder — and wow, the results were super clean. The letters are bold, not too deep, and the mold doesn’t require much release spray. I made a full name keychain and a date tag for a pet collar. They look store-bought.

Pros:

  • Smooth interior finish

  • Even letter spacing

  • No major air bubble issues

Cons:

  • Doesn’t include symbols

  • A and R cavities are tricky to fill without spill

Comparable US molds go for $10+, and this one was under $4. Definitely a solid buy and great for beginners or anyone selling personalized resin goods.

US $1.19

🟣 Large Silicone Mat for Craft & Resin Work

I bought this multi-use silicone mat mainly for resin pouring and to protect my worktable. The size and color options stood out (I picked the smoky grey), and it looked thick and non-slip.

Delivery was lightning fast — 9 days total. It came rolled but flattened out overnight without any creasing.

This mat is amazing. It catches resin spills, doesn’t let anything stick, and wipes clean with just baby wipes or alcohol. It’s also heat-resistant, which I tested with a mini torch. No melting or warping. It’s doubled as a baking sheet liner once or twice, too.

Pros:

  • Large, thick, non-slip

  • Super easy to clean

  • Versatile for resin, clay, or baking

Cons:

  • Has a slight chemical smell when new

  • Not perfectly rectangular (edges are a bit wavy)

At around $6, this is way cheaper than comparable US mats that easily hit $15–$20. It completely delivered, and I’d definitely order a backup.

US $2.57

🟣 Heart, Leaf & Moon Earring Mold

This themed mold with hearts and moons felt like a cute add-on for more whimsical jewelry. I went for it mainly for the crescent moon and leaf shapes.

The mold arrived bubble-wrapped in about two weeks. No damage, though it had a very slight plasticky smell initially.

Using it was fun — the fine details in the leaves came out beautifully with mica powder, and the moons look elegant with glow-in-the-dark pigment. Perfect for celestial-themed earrings or keychains.

Pros:

  • Unique shapes

  • Very crisp detail, especially leaves

  • Holds pigment well

Cons:

  • Small cavities are hard to fill cleanly

  • No loop indicators for jump rings

At under $3, it’s a cute and budget-friendly mold. Much better value than the nearly $12 I’d pay for something similar on Amazon.

US $1.65

🟣 Pet Photo Frame Keychain Mold

This pet frame mold caught my eye because I wanted to memorialize my cat with a custom tag. The cat and dog silhouettes were a plus.

It came flat-packed with no deformation. Took 13 days to arrive.

I added a photo printout with resin and sealed it with a UV topcoat. It worked! The space fits a small photo perfectly, and I added a name with vinyl on the back.

Pros:

  • Clear shapes

  • Works well with micro photos

  • Durable feel

Cons:

  • A bit shallow

  • You’ll need patience aligning photos

Easily worth it at under $2. I saw similar ones on Etsy for $10+. A meaningful and functional mold.

US $1.17

🟣 Rectangular Storage Tray Resin Mold

I’ve been meaning to make my own catchall trays for rings, so this rectangle tray mold was an easy choice. The shape looked versatile and the reviews were solid.

Delivery was just under 2 weeks, packed carefully.

I made a terrazzo-style tray with pastel chips in clear resin. It came out smooth, no need for sanding. It’s slightly flexible but holds shape well when cured.

Pros:

  • Clean lines, very minimalistic

  • Easy to demold

  • Ideal for soap trays, jewelry, or candles

Cons:

  • Slightly smaller than expected

  • One edge had a faint ridge (needed filing)

At about $4, it’s much more affordable than $18+ trays sold on craft sites. Definitely recommend.

US $1.19

🟣 Dog Bone Tag Mold

As a pet owner, I couldn’t resist the dog bone keychain mold. I wanted to make custom ID tags with names and contact numbers.

Shipping was surprisingly fast — 10 days from dispatch. Mold arrived pristine.

I used color-shifting pigments and added names in vinyl. It looks custom and durable. The bone shape is universally cute, too.

Pros:

  • Easy to fill

  • Great gift idea

  • Durable silicone

Cons:

  • Just one bone shape

  • No pre-marked ring hole

Still, at $1.50, this mold is a great tool for custom pet gifts. The US price for a similar mold runs around $8.

US $1.74

🟣 Large Rectangular Tray Mold

This large tray mold was one of the more “splurge” items in this haul. I wanted something big enough for a serving tray or statement decor.

It took about 14 days to arrive and was well-packed in a plastic sleeve.

I did a beach theme pour with layers of blue resin and white foam effects. It turned out stunning. The mold gave a glossy, smooth finish and the edges needed zero polishing.

Pros:

  • Thick and durable

  • Beautiful gloss finish

  • Perfect size for a serving tray

Cons:

  • Takes a lot of resin

  • Heavy when filled

Worth every penny at $7. US trays this size go for $25–$30 easily. Will use again for gifts.

US $1.64

🟣 Mini Letter Resin Mold – Uppercase

This mini letter mold is perfect for making tiny initials for bracelets or bookmarks. I liked that the letters were compact but not illegible.

It arrived with a faint powder coating (normal for some silicone), but wiped clean easily.

Use case: paired letters with pressed flowers and metallic flakes. They cured without bubbles and were super cute as tiny charms.

Pros:

  • Small size perfect for dainty items

  • Easy to clean and demold

  • Great for multi-letter combos

Cons:

  • No numbers

  • S and B can be hard to align straight

At around $2, it’s a solid purchase — much cheaper than the $10 sets I’ve seen locally.

US $1.91

🟣 Multi-Style Earring Mold – Fancy Shapes

Last but not least, I wanted to try this fancy earring mold with abstract and organic designs. I liked the fluid lines and asymmetry.

It arrived within 12 days, no odor, very flexible.

I tried it with color-shift resin and some gold flakes. The results were striking — they honestly look boutique-level. The mold surface gives a glassy finish without polishing.

Pros:

  • Trendy, artsy shapes

  • Big mold with multiple pairs

  • High-end finish

Cons:

  • No holes for jump rings

  • Some shapes are too large for earrings

Still, for $3.50, this is one of the best-designed molds I’ve used. It easily competes with $15+ molds from big-name craft stores.

US $1.19

Overall Impressions

Honestly, I went into this AliExpress haul a bit skeptical, expecting at least a few flops — but every single item surprised me in a good way. Most of the molds were better quality than I’d get at craft stores in the US for 3–5x the price. Delivery was consistent, packaging was careful, and nothing arrived damaged.

I’d absolutely recommend these products to fellow resin crafters, whether beginner or advanced. I’ll be ordering more soon — probably some seasonal shapes and a few deeper molds for layered pours. For the price, it’s hard to beat.
