The Rigid Card Holders are all designed to accommodate the ISO Credit Card size – (53.9 x 85.7mm); no other size of card is suitable; these holders will provide strong rigid protection for the card and in some cases protection to the surface of both sides; different holders are supplied in different colours and some holders will accommodate more than one card. The rigid holders have either slots or holes (or sometimes both) to enable them to be worn with neck chains, lanyards or clips.
