Popular reviews have these as lasting longer than the brass tacks by others.
Brass tacks for securing your work to stretcher bars. Includes 60 tacks and built in metal tack remover. Ever so slightly larger with a slightly sharper point between Toraya tacks and Clover tacks. If you mount canvases frequently you may want to consider purchasing a Cor-Jac tool available separately. ( It saves your thumbs and makes it so much easier to mount.). You may find a screw driver helpful to slide open the lid.
