Shrinky Plastic Sheets Keychain Kit Review – 125 Pieces Tested

Quick Verdict

After running 20 of the 125 pieces in this Shrinky Plastic Sheets kit through my kitchen oven, I can tell you this: it is a genuinely fun craft activity that delivers on its promise without requiring any prior experience. The 11.4" × 8.0" frosted PVC sheets color smoothly, shrink predictably, and produce sturdy keychains that feel like real accessories — not classroom throwaways. At the price point, the bulk value is hard to argue with. Score: 4.3/5.

What Is the Shynek Shrinky Plastic Sheets Kit?

It arrived on a Thursday, sat unopened on my craft table for two days, then finally got its turn on a rainy Sunday when my 8-year-old was climbing the walls. The box promised 125 pieces. I was skeptical — budget kits often mean you spend half the time running to the store for things that should have been included. But shynek actually delivered on the parts list. Twenty blank Shrinky Plastic Sheets, 12 colored pencils, a pair of scissors, a hole punch, tweezers, 20 keyrings with chains, 20 lobster clasps, and 50 jump rings. Everything you need to make keychains, charms, and small pendants — no shopping required.

These are heat-shrink plastic sheets made from PVC. One side is frosted, which grips colored pencil wax better than you might expect. You draw on the blank sheets, cut out your design, punch a hole, and bake. The sheet shrinks to roughly 20% of its original size and thickens up in the process, becoming surprisingly rigid. It is essentially shrink film art — the kind of craft that has been around for decades under brand names like Shrinky Dinks, but available here as a budget-friendly bulk kit.

Key Features

Hands-On Review

Let me walk you through what actually happened. We started with sheet one: a simple star design drawn in pencil, then colored in with the bundled pencils. The frosted surface took the color without any smearing or skipping — I was relieved, because cheap shrink film often repels wax-based media. Cut it out with the included scissors, punched a hole near the top corner, and slid it into a 300°F oven on a sheet of parchment paper.

Watching the curl is the best part. The sheet lifts at the edges, curls inward like a corn chip, then slowly flattens out over about 90 seconds. I pulled it out, let it cool for 30 seconds on the counter, and held it up. What started as a 3-inch star was now a 0.6-inch charm, roughly 3 mm thick and rigid as a plastic chip. It looked — and I say this with zero exaggeration — like something you could buy at a boutique gift shop.

By sheet three, my daughter had abandoned the bundled pencils for her own Prismacolors, and the difference was immediate. Brighter colors, cleaner gradients, much less frustration when filling in small areas. The 20% shrinkage means anything under roughly 5 mm in your drawing will vanish or become a blob. By sheet ten, we had stopped trying to be intricate and started embracing bold shapes — big letters, simple animals, geometric patterns. Those were the ones that looked best post-bake.

The hardware is perfectly serviceable. The jump rings need the included tweezers to open and close — they are tight, which is actually good for durability. The lobster clasps are colorful plastic, not metal, which keeps the finished look playful rather than industrial. We attached six charms to a single chain keyring and hung it from a backpack. Three weeks later, all six are still intact and the PVC has not cracked or scratched despite daily handling.

Who Should Buy It?

Kids aged 6–10 who love hands-on crafts are the obvious audience. The process is simple enough for beginners but satisfying enough to keep them engaged for a full afternoon. There is a real payoff at the end — something they can actually use — which is more than you can say for most coloring pages.

Parents looking for a screen-free rainy day activity will find this kit genuinely useful. It requires adult involvement only for the oven step, so you are not just supervising — you can participate. Some of the best moments during our testing came from us working on designs together.

Teachers and classroom leaders running art sessions will appreciate the bulk quantity. Twenty sheets and enough hardware for 20 finished keychains means every student walks away with something. At roughly a dollar per student for the sheets alone, the math works.

Skip this kit if you are a serious crafter looking for archival-quality materials — the PVC sheets here are functional but not museum-grade. Also skip it if you are buying for a child under 6, because the cutting, drawing, and oven steps all require motor skills and supervision that most toddlers simply do not have.

Alternatives Worth Considering

Basic DIY Shrink Film (no kit): If you already own art supplies, buying shrink film sheets in bulk from an art store gives you better-quality PVC at a lower per-sheet cost. You lose the all-in-one convenience but gain control over materials. Good for regular crafters who know what they want.

Pre-printed shrink art kits: Kits that come with pre-drawn designs to color save time and produce more polished results for beginners. They are less creative but much easier for young children who struggle to draw their own images.

FAQ

Final Verdict

The shynek Shrinky Plastic Sheets keychain kit is exactly what it claims to be: a generous, beginner-friendly craft set that produces real, usable keychains without a steep learning curve. The 20 blank sheets and bundled hardware give you everything needed for a productive afternoon, and the results are more impressive than the price tag suggests. Will you get museum-quality art? No — this is PVC shrink film, not archival material. But for kids, parents, and classroom teachers looking for a satisfying hands-on activity, it hits the mark. If you have the supplies already, buy just the sheets. If you want everything in one box to open and start immediately, this kit earns a spot in your cart.
