Simply pull to use the card or key, they will easily retract after use. Retractable Card Holders come in a full range of colours and are available in budget and premium styles. There is a heavy duty Yo-Yo for those with a need to carry several keys/cards. Two ski pass Yo-Yo styles are also available.
