Slim profile is great for storage!
This scalloped scallop paper edger punch is one of my favorites among the EK Success slim profile punches. I've always loved using edge or border punches to embellish my cards. This line of punches has some fun new designs. They punch well. I've not had any trouble using cardstock. The more detailed designs can be a bit harder to punch, as expected, but I've managed to use them with cardstock, too.
What really puts these punches at the top of my list is the slim profile. They're made so that they can be locked into the shut position when not in use, making them much easier to store than the other border and edge punches out there--they take up less space, too. I have several of these punches and have been using them since they were first released. No problems. I'd definitely recommend them!
