Using these unfinished wood candle shapes is easy. First, peel off the protective paper backing that comes on most of the crafts. This backing is there to protect the wood during the laser - cutting process and shipping. You can customize these shapes by adding a hole if you need one. Just send a message to the seller with the size and location of the hole you want. When it comes to crafting, you can paint, stain, or decorate these shapes however you like. They're made from cabinet - grade Baltic birch plywood, which is a sturdy and high - quality material. As for maintenance, keep them away from excessive moisture to prevent warping. If you want to store them, make sure to keep them in a dry place. And remember, if you have any questions about these products, don't hesitate to click the 'Message Seller' button for help.
