Using this unfinished wood Puerto Rico shape is a breeze. First, peel off the protective paper backing that comes on most crafts. This was there to protect the wood during cutting and shipping. You can use it for a variety of DIY projects right away. If you need a hole in it, just tell us the size and where you want it, and we'll add it for free. When it comes to the size, you have options from 1 inch up to 24 inches. The wood is made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch thicknesses. If you want a different thickness, just ask. To maintain it, keep it in a dry place away from direct sunlight. Since it's unfinished, you can paint, stain, or decorate it as you like to fit your project. Have fun with your DIY and if you have any questions, don't hesitate to contact us.
