A credit card holder (mine holds 4!) with a sliding top and magnetic. For holding cigarettes, dollas and more! While supplies last!! It has 4 spots for 2mm tall by 5mm diameter magnets. just make sure they are facing the proper direction and use some (superwoodelmersrubberwhatever) glue to secure them.
I designed supports to help with the bridging.... this is not my favorite design but it does function and looks mildly not boring. Expect a redesign soonish!
Custom designed supports included with purchase!!!
