Eenie meenie minie mo. We love this BABY sized trinket. It's perfect for absolutely anything and everything. It has a slight edged to it and you'd be able to fit an espresso cup if you plan to use it as a coaster. Please take note that the piece you'll receive will not be 100% exact copy of the image here. No two pieces are the same, no speck will be in the exact spot as they are handmade and that's what makes each piece so special! Wipe dry with a damp cloth. Not dishwasher-proof! Wipe clean all colourants like coffee/tea/wine immediately. Measures 80mm ( outer diameter) x 5mm (height) Weighs approximately: 50g B21
