I have drink coasters (3.5 inches by 3.5 inches). I make them and sell them. I can do a variety of different color stains and seals. Can even put custom decals on them for more personal customization (just send a picture of the design and color of choice). The price is $15 for a set of 4 plain ones and $20-25 for a customized set of 4. (Ones in the picture are burnt and sealed and the light ones are just natural and sealed). Message me with what you want and I’ll make it up
