These beach scene coasters are hand made and no two are ever alike. Each coaster is made with real California sand, resin and has a real shell imbedded on the beach. Imagine yourself relaxing ocean side finding seashells on a sandy beach in an explosion of color and depth of blue waves. I use multiple layers of resin, shimmering pearlescent colors and inks to create the translucent depth of the ocean waves crashing on the beach. They have a level clear layer on top to give the ocean depth and keep the coaster flat. Each coaster is about 4” diameter and has a slight raised edge to prevent liquids from spilling over. They are mounted on a cork base. These are made to order and may be slightly different than the ones pictured. The shells will vary and not all sets have the starfish. ****I can do customized versions of this and you can supply the sand from your favorite beach! It takes 3-4 weeks to complete. Contact me for further details. Keep all resin products out of direct sunlight to prevent fading of color. Resin coasters can not be used with high heat. These are made for cold/luke warm drinks *This is a one of a kind work of art. Any slight imperfections are part of the process and contribute to its unique quality. ***Please make sure the desitination address is a secure location.
