Concave Corner Punch
These little punches make a big impact on cards or albums. I was resistant to buying because of the space they take up. I caved however and bought a variety of these. The concave corner rounder is my go to, but I also have two basic corner rounders and a scalloped corner. EK Tools seems to be much sharper, more sturdy and they do close up flat to take the least space possible in my drawer.
Happy stamping and/or camping!
