After a bathroom renovation, I decided to go 'coastal' and add accessories along that vein. I don't like nautical but want to stick to the sand and surf.  This piece is bigger than you would expect and heavier. It comes unframed. You can put it in a shadow box or it does have groves in the back to hang it. I love that it looks so realistic. I also bought the starfish as the mate to this piece.
A word of caution-the first one came broken in three pieces. The shipping department was asleep that day and they didn't put Bubble Cushion around both the sand dollar and the starfish. All I had to do was call Wayfair and tell them what happened and POOF!  A new one was sent to me, no charge and all was right with the world. Wayfair's customer service is excellent.
