The 4 inch octagon is constructed of high quality baltic birch plywood. We measure this octagon from corner to corner to get the 4 inch measurement. The distance between the flat areas are 3 11/16 inches. Sold in a package of 10.
We cut all of our own unfinished plywood cut outs in our shop. We do not cut the shapes until you order them. Always in stock and made in the USA. We can make any changes to this or any other shape that you need, just contact us and let us know what it is that you need. We can make the shapes larger or smaller, add holes or we can also engrave on the surface of the wood.
