My shadowboxes are not indestructible, they are delicate and at the mercy of time, gravity and the elements. These pieces are primarily made of paper. Although I use archival paper, it may fade slightly or bend slightly over time. extreme temperatures could hinder the integrity of the piece. When you buy a shadowbox, you are buying a piece of art that may change over time. I have been making these boxes for several years and only once have I been contacted about making a repair(a very easy fix), they are well constructed but I wanted to explain the risk involved. I don't ship shadowboxes, they are full of tiny needles and under glass. Unlike a painting, if a shadowbox were dropped, it would be ruined. Shadowboxes can be purchased at shows, or, if you live in the Pismo Beach/San Luis Obispo area, delivered.
