Product Information: Sqube coin tubes offer a secure storage solution for silver ounces. With an innovative twist function, the lid is both securely lockable and easy to open. A customised intercept foam in the lid provides active protection against coin tarnishing for up to 15 years. In addition, the resilient effect of the foam ensures scratch protection for the top coin. Thanks to the non-slip lid, the Squbes can be stacked without any problems. The outer dimensions are 87×50×50 mm.
