Leuchtturm Intercept Box SL 50 for 50 slabs (345237)

This box actively protects your coins from oxidation thanks to the INTERCEPT® material inside. For 50 slab coin capsules (EVERSLAB, QUICKSLAB, PCGS, NGC, etc.). Suitable for coins and medals made of copper, gold, silver, brass, etc. Overall size: 321 x 152 x 97 mm (12 5/8 x 6 x 3 7/8"). Box material: cardboard (2 mm thick) 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. *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.
