Proper preparation of products packaged in plexiglas or made of plexiglas is required to prevent damage throughout the fulfilment process.
All items shipped to an Amazon fulfilment centre that are made of or packaged in plexiglas require a label at least 2"x3" that states that the product is plexiglas.
These labels help distinguish plexiglas products from products that are made of glass, which require special packaging and handling.
