Here is a leather card and ID holder with 20 “pages” that will hold up to 40 business cards or credit cards with two in each slot back to back or up to 20 cards with one card per “page”. Additionally, there is an ID card holder inside each cover for a total of two ID card holders. If you purchase more than four at one time, please wait for me to send you an invoice so I can be sure you’re not overcharged for shipping. Thank you for looking!
