Thank you for your question about MMM17024CABPK Command™ Poster Strips. Each carton contains 100 4-packs for a total of 400 strips. That works out to about 14¢ a strip.
It takes four Command™ Strips to hold up a pound, or to hang a standard poster. Individually, each strip supports up to 1/4 lb.
Hope this answers your question!
