The Corner Chomper has two sizes available, which is fantastic! I put together a bunch of tins at Christmastime to hold gift certificates and having the larger size corner rounder would have been great for making the Designer Paper inserts since the tins I purchased had larger corners and I ended up having to hand cut all the corners. You can also round several sheets at a time, making corner rounding even faster when you're working on multiple projects. If you're interested in purchasing the Corner Chomper, visit Scrapbook Pal for both the tool and the carrying case. Scrapbook Pal offers free shipping on orders over $25.00 and they always have good deals on Tombow Adhesive refills and Cricut Cartridges. I hope you enjoyed this little product review!
