JT21 staples are the T50's little brother. Although often referred to as light duty, theres really nothing light about them. Built with the same quality and precision as the T50, these staples utilize a thinner wire in a smaller staple format to deliver great holding power. They are exceptionally easy to fire, making JT21 staples a favorite with crafters, women and those with limited grip strength. Used for general home repairs, crafting, art projects and upholstery.
