The Key Chain Holders are equipped with very strong magnets that hold key rings as well as a handful of other metal items. (ie. bottle openers, metal pens, wine corkscrew, scissors, sewing needles, etc.) Keys themselves are not magnetic; however, key rings are magnetic and the magnets hold a surprising amount of weight.
Approx. dimensions:
5 Magnet: 9 1/2" x 3 1/2" x 1/2" thick
4 Magnet: 7 1/2" x 3 1/4" x 1/2" thick
3 Magnet: 5 1/2" x 3 1/4" x 1/2" thick
