This is part of a collection. This one says August on it. I don't have the whole collection. Could be in celebration of a birthday month for someone who likes Trinket boxes. 3 1/2" H & 3 3/4" W I have another one listed that is for May. If you want, make a bundle of the two, and I'll give you a great deal! Made of sturdy resin material and is not glass. 😀 Clean, Smoke-Free Home! 🚛 Fast Shipping! 👌 Fair offers accepted! 🌍 May use recycled or reused boxes, mailers, and packing materials.
