Pack of 6 Lighthouse Quadrum Intercept 16mm diameter square snaplock coin holders.
Lighthouse Quadrum Intercept holders feature Lighthouse's Intercept Technology, which actively protects your coins against tarnishing.
Basic capsules or snaplocks limit a coin's exposure to ambient air and moisture - which is a good start - but the Lighthouse Intercept holders take it one step further.
The highly porous, copper-based Intercept material neutralizes harmful atmospheric gases inside the capsule which creates a non-corrosive micro-climate for the coin.
Actively prevents coins from tarnishing for up to 15 years.
Lighthouse Intercept material is non-toxic and doesn't leave any oily build-up or residue on the coin.
Lighthouse Quadrum capsules are archival safe, crystal-clear, scratch-resistant, and durable.
They are made of rigid plastic that snaps together securely, yet is easy-to-open.
Outer diameter : 2" x 2" (50 x 50 mm).
Size of hole in foam insert : 16mm
Works with coins up to approximately 3mm thick.
