These unfinished wood candy kiss shapes are great for DIY projects. First, if you want a hole in the shape, tell the seller the size and where you want it before the shipping. Once you get the product, peel off the protective paper backing. You can use them right away for your craft projects. As for maintenance, keep them in a dry place to prevent warping. If you get a thicker piece, it may be sturdier but harder to cut or shape, so use appropriate tools. And remember, if you have any issues or need more info, just message the seller.
