Using these unfinished wood apothecary potion flask shapes 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, just tell us the size and where you want it, and we'll add it for free. You can use these shapes for all sorts of crafting projects. They come in different diameters from 1 inch to 36 inches, so you can pick the size that suits your project best. The wood is sanded and has lightly burned edges from cutting, giving it a nice, natural look. When it comes to maintenance, keep the wood in a dry place to prevent warping. If you want to paint or stain the wood, make sure to use products suitable for Baltic birch plywood. And if you need a different thickness than the 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) we offer, just send us a message.
