Pegboard hooks, small size (Kensington)

My club sponsors an annual art show as a community service to local artists. We use pegboards for displaying the art. For some of the artwork we need more small pegboard hooks, like the one pictured. We have not been able to find them from any store that sells hooks, so we're hoping that someone has some they no longer need. The hooks are about an inch tall and 1.5 inches from one side to the other. Thank you!
