Leuchtturm ULTRA coin capsules Intercept 38 mm, pack of 10 (359432)

Inner diameter:38 mm ULTRA Intercept – the only round coin capsule worldwide with active protection against tarnishing! Thanks to proven technology, the coin capsules ULTRA Intercept offer a completely new kind of coin collecting. The foam ring inside the capsules with a thickness of 3 mm 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 capsule. 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. Available for all coins with a diameter from 26 to 41 mm (in millimeter steps). *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 capsules / boxes) 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.
