Leuchtturm Intercept L 180 Box for coin sets, postcards, letters and documents up to 80 x 160 mm (345417)

This box actively protects your collection from oxidation and ageing thanks to the INTERCEPT® material inside. Suited to protecting coins, medals and paper. Suitable for coin sets, postcards, letters, stockcards, documents etc., up to 180 x 160 mm (7 x 6 1/4") in size. Overall size: 331 x 160 x 185 mm (13 x 6 1/4 x 7 1/4"). The way an INTERCEPT® box works is based on over 30 years of patented INTERCEPT® technology: the copper particles contained in the material permanently bond with corrosive gases and create a neutralised atmosphere in the shortest time possible, protecting the coins and documents from tarnishing (Guaranteed protection up to 15 years*!). This method has been proven in line with approved DIN, EN, ISO and ASTM standards. In order to prolong the effectiveness of the INTERCEPT® box beyond 15 years, it is recommended that you close the box immediately after use and avoid opening it frequently. Box material: cardboard (2 mm thick) *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.
