Frame size: 9 x 9 cm The surface does not have an acrylic plate, and the original plate is set inside. I create these with care, but there may be some adhesive overflow, and there may also be natural chips or imperfections in the sea glass. Additionally, there is a possibility that pieces may come loose after shipping. In that case, I apologize for the inconvenience, but please reattach them with adhesive yourself. Please purchase if you understand that this is a handmade item. m(_ _)m Sea glass art Bird, flowers (red & blue)
