***We offer combined shipping when you purchase more than one item from our Solid Factory store.***<br><br>This card tray organizer/holder was initially made to keep board game cards, well, organized during gameplay. It grew in popularity so much so that we received a request to fashion a tray that would accommodate 3” x 5” index cards. And, thus, this product was born.<br><br>Keep your 3” x 5” index cards organized with these trays. Each set includes two trays, 3 slots each tray, totaling 6 slots altogether. Snap the two trays together to assemble cards in two tiers, or keep them aligned side-by-side. Either way, your cards are kept organized and easily accessible!<br><br>Card Slot Dimensions: 78 mm (width) x 113 mm (depth) (approx. 3” x 4.4”)<br><br>Thank you,<br> <br>Team Solid Factory <br><br>Check out our other products at https://www.amazon.com/stores/node/13917242011?_encoding=UTF8&field-lbr_brands_browse-bin=Solid%20Factory&ref_=bl_dp_s_web_13917242011
