This is a set of customizable coasters handmade and I think they look like a pretty awesome product design. The customizable coaster set contains four coasters, each coaster is made of solid stone, and comes with a cork board backing in order to prevent it from scratching your furniture. Most importantly, you can freely pick up your favorite Instagram photos, sending them to the crafter for your own Instagram photo coasters. When drinking, you can conveniently share the awesome photos with your friends. What do you think of the idea?
