Using these unfinished wood drum stick shapes is easy. First, peel off the protective paper backing that comes on most of the crafts. This was there to keep the wood safe during laser cutting and shipping. You can customize the shapes according to your project needs. If you want a hole in the shape, just tell us the size and where you want it, and we'll add it for free. For the different sizes available, you can choose a diameter from 3 inches up to 36 inches, depending on what your project requires. As for maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping. You can sand it further if you want a smoother finish, and then paint or stain it as you like. If you have any questions during the use of these products, don't hesitate to message the seller.
