These card holders are a great addition to game night! Though we thoughtfully designed the cards to be easy to read when held, the racks are great for spreading out your cards and keeping your hands free while you play (making it easier to cheers for Bird Bam!). Though not necessary to play with your Play Away deck, we think it adds to the experience and feels even more like playing with traditional tiles! Also great for little hands or those who may have trouble gripping cards. Use them for any card game- Gin, Rummy, Bridge, etc! Sold as a set of 4.
