This insert for coin tubes is perfect for safely and securely storing your coins long-term. The insert was designed for Münztube Sqube (Art. 6242 and Art. 6243). The additional foam can also be used with other coin tubes—just place it between the top coin of the full tube and the lid. The insert can also be easily cut to fit smaller tubes (e.g., 1/10 and 1/4 oz. Britannia).
The secret of INTERCEPT® is that it traps corrosive gases before they can react with the coin metal. This process happens at the molecular level instantly. Unlike conventional methods, no layer forms on the coin surface.
