This is the metal chain tested and approved by Claudia to add to the boxes to support the lid, as seen in the pictures.
After testing many types she finally got this one to work, as it's strong and also beautiful.
This is a pack with 3 feet of this chain. To use as support for the lid of the boxes, you will need extra hardware - the pack of hooks and screws that you will find here (and it's included in the Hidden treasures box - retreat 25):
Color is antique brass. Size of each chain is 5 x 7mm and it's 3 feet long (enough to use in 5 boxes)
