These ornaments are designed to hold a small amount of beach sand as a keepsake. Made from 4 separate layers of material. Name drop on the acrylic layer is included in the price. Available empty or prefilled with white sand shown in the images. These are designed and cut in our small home shop from solid wood stock, and shipped to you with an oil based finish. With that said, each product has its own unique characteristics based on the varying grain and colors found in any natural product. Dimensions: 3.25" dia., 3/8" thick, cut from solid wood (no plywood or veneer wood). Made from walnut. This blog post goes into the inspiration behind the design as well as instructions on how to fill and plug the opening. https://cottonseedmarketplace.com/blogs/news/sand-keeper-ornament
