Square plastic capsule Quadrum for silver coins Philharmoniker
Quadrum square capsules have identical outer dimensions for different coin sizes inside. This allows you to organize coins of different diameters into one system or insert everything into a universal gift box Quadrum. Variability is ensured by a black insert of flexible EVA foam that defines and protects the deposited coins.
This capsule size is primarily recommended for both Philharmoniker silver coins.
