Choose between:
Acrylic material:
Sturdy clear material. Non-scratch resistant.
Note: The acrylic rings have protective foil on the back which needs to be peeled off before use
Glass material:
Glass is a premium material, the inserts are made of tempered (reinforced) glass which is scratch, chemical and water resistant. It also withstands sun and temperature differences. Glass is therefore a better option and more durable in the long run.
These inserts will fit most portable machines, including Royal, Underwood, Erika. Before you buy, make sure to measure the diameter of your key rings. Up to 2mm difference is tolerable and the inserts will fit perfectly.
