This is a 3D printed wallet that will hold (12) 1-gram Valcambi silver bars and a 39mm silver round. The top slides in and there are hidden magnets to help hold the top in place. This was designed around the 1-gram Valcambi silver bars. I have not test fitted any other 1-gram bars, so others are not guaranteed to fit. The silver bars and 39mm round are a tight fit to insure they don’t fall out. Dimension: 4″ x 2.5″ x 3/8. 1 – Silver Wallet. 12 – 1-gram Valcambi bars. 1 – 39mm Silver round.
