SQUBE Coin Tubes for upto 20 Silver & Gold 1 Oz Coins

The square Sqube coin tubes offer a secure storage solution for silver ounces.

Thanks to the non-slip lid, the Squbes can be stacked without any problems and the innovative twist function allows the lid to be both securely locked and easy to open.

The unique feature that sets the Squbes apart is the tailored intercept foam in the lid which provides active protection against coin tarnishing for up to 15 years.

The foam's springy texture provides scratch protection for the top coin

The outer dimensions are 87×50×50 mm.

Intercept Technology
The foam insert is based on the patented Intercept technology, which is proven for more than 30 years. The copper particles in the material bind corrosive gases permanently and as a result neutralise harmful atmospheric substances inside the Sqube.
This protects the coins from tarnishing. Guaranteed protection up to 15 years*!
The effect was verified by the reliable norms DIN, EN, ISO and ASTM amongst others.
*The effect duration will significantly exceed the specified 15 years under normal storage conditions! Very unfavorable conditions (e.g. exceptionally high air pollution or the constant opening of the Sqube) could cause the effectivity of the Intercept materials to be used up prior to the 15 years.
When the potential of the material has been exhausted, the film will turn a dark grey to green color (not the coins!). When this discoloration occurs, you should replace the product with a new one.
