Using these unfinished wood goggles - shaped crafts is easy. First, peel off the protective paper backing that's there to keep the wood safe during laser cutting and shipping. Then, you can start your craft project right away. If you need a hole in the shape, just tell us the size and where you want it, and we'll do it for free. 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 the surface is clean. Also, since we make these by hand in the suburbs of Pittsburgh, expect high - quality details. If you have any questions while using the product, don't hesitate to click the 'Message Seller' button, and we'll assist you.
