No matter if ancient, curved, or in a triangular, the MAGIC CAPSULES S are the perfect storage solution for your irregularly shaped coins. The special membrane inside the capsule is transparent, flexible, and conforms to the collectible, giving it the appearance to 'float' so that it can be viewed from front and back. Suitable for coins up to diameters up to 1' (27 mm). Outside diameter: 1 3/8" (36 mm). Capsule made from premium clarity, scratch resistant polystyrene.
