Sold in sets 4, the AVF Bullseye Acrylic Coasters are a fun way to add color to your table. They have been laser-etched, handcrafted with the finest quality acrylic and are finished off with a small, clear rubber bumper to protect your table that also allows you to stack them on top of each other without scratching the acrylic. When stacked up, they make for an interesting sculpture object to add color to your table.
