I use my expired credit, ATM, and assorted plastic cards for several modeling purposes. I cut them into various-sized pieces to serve my needs. I use strips to mix paint and epoxy glues. I use square pieces to hold a spot of super glue to dip into. Sometimes a piece can be glued out of sight to reinforce thin hulls and seams. I also use them for scratchbuilding.
Plus, you don’t have to worry about shredding your cards or someone you don’t trust getting hold of them.
