These Velcro attachments are ideal for hanging posters without marring your walls. They are only 1/16" thick, with an adhesive backing that can be applied to smooth surfaces (such as drywall or painted wood) and later peeled away without a trace.
Simply apply the 1-1/4" loop square to the wall and the 7/8" hook coin to the poster. The coin's smaller size allows for slight hanging adjustments without reapplying the square.
One package includes 12 pairs of squares and coins, enough to hang three posters weighing less than 1/4 lb.
