Pier One Porcelain Coasters Butterfly Set of 4

Pier One Porcelain Coasters Blue White Butterfly. Measures approximately 4" x 4". Set of 4 with the box. Has been opened but never used. I will list them used since the box has been opened. No chips, cracks or scratches on the usable surface. The back has manufacturing flaws but they're minute (see pic #3).
