Description
QUADRUM Intercept represents a completely new technology in the world of numismatics. The material actively protects the coin against oxidation. The foam insole is based on Intercept technology, patented more than 30 years ago. The copper particles in the material neutralize harmful substances existing in the atmosphere, thus protecting the coins from discoloration (protection guaranteed for up to 15 years). The efficiency has been certified by din , EN, ISO and ASTM regulations, among others. QUADRUM Intercept represents a completely new technology in the world of numismatics.
