We're 99% sure your friends and family won't have a set of these! Our coaster sets (4) are THE perfect gift you've been searching for. We suggest purchasing two sets because it's likely you'll want a set for yourself!
Dimensions are approximately 3" round, and each has a small lip to prevent water from escaping. Coasters come with a stamped cork base to prevent scratching and slipping. Recommended to dry each after use, use a damp cloth and dry after to clean.
No two are alike and plastic colors inside will vary.
Occasional small bubbles may be apparent; we choose to think of them as bubbles from the sea!
