The picture below shows CM’s square, circle, and puzzle sizes from their discontinued shape makers; and it also shows the new square, circle, and puzzle pieces from their new tool. I didn’t think I needed another square, circle, or puzzle punch, but I was wrong. This tool is sooooo convenient and easy to use. The cartridges slide in and out easy and punching them is almost effortless. Just my kind of tool! thank you for looking today!
