The insert of the capsule is equipped with a ‘snail’, i.e. rings in different sizes. This allows the capsule to be conveniently adjusted to fit coins with diameters between 16 and 41 millimetres, meaning collectors do not have to purchase capsules with different diameters in advance. The rings have been selected for common coin sizes. This product offers collectors maximum flexibility and proven security and quality.

The inner diameter can be adjusted in the following steps thanks to removable foam inserts:

16.25 mm, 19.5 mm, 21.5 mm, 23.5 mm, 26 mm, 28 mm, 30.5 mm, 33 mm, 35 mm, 39 mm & 41 mm
