Using these unfinished wood popcorn shapes for your food crafts is a breeze. First, peel off the protective paper backing that's on most of the crafts. This was there to keep the wood safe during laser cutting and shipping. If you need a hole in your shape, tell the seller the size and where you want it, and they'll add it for free. You can use these shapes in various DIY food - related projects. They come in different sizes from 3' up to 36', so choose the one that fits your project best. When it comes to maintenance, keep the wood away from excessive moisture as it might warp the plywood. Since they're made from cabinet - grade Baltic birch plywood, they're pretty durable. If you want a different thickness than the available 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inches, just message the seller. And don't worry about waiting long for your order, as they'll ship it within 24 hours, or it's free!
