We offer two styles of business card cases. The first style is secured with a leather strap and you simply tuck the cover under the strap. The second style secures the cover with a snap. The strap style will hold about 20 standard size business cards while the snap style is a bit thinner and will hold about 12 standard size business cards. Both are made out of top quality leather and finished with a professional oil dye. Made to last... handy and easy to use!
