Shipping artworks behind or made from glass is at the artists' discretion.
At Bluethumb we cannot take on any liability for loss or damage while in the artwork is in transit. As insurance companies do not insure any packages containing glass.
If you would like to go ahead with packing your framed artwork, please make sure the corners of the artworks are supported with thick cardboard. Wrap the artwork three or four times with bubble wrap.
Once the artwork has a few layers of bubble-wrap covering it, place in a larger cardboard box. Fill all free space in your box with more blue-wrap, so the artwork doesn't move whilst in transit. There's never such thing as to much bubble-wrap!
Once the box is wrapped up attach fragile stickers and/or fragile tape.
