AIDOX PP64B LG-RED Angle 10mm Eater Corner Rounder Large (Fоur Paсk)

Seems to work well. I bought both sizes (5mm and 10mm) ... in case you're wondering the difference between the two, here's a comparison using a dime as a scale of reference.

We used this to round the corners on the program fans we made for our wedding. Great product. Easy to use but makes a nice difference in the finished product!

Excellent product, at a great price. I made laminated note cards (3mil thick), but the sharp corners made the cards a pain to use. I was concerned that this rounder wouldn't work well w/laminated pages, but it does a beautiful job. The 10mm corner is perfect for a mostly rectangular card, but only cut one laminated page at a time.I will be looking for other projects to round, and for other punches of this brand.

I love the low profile and sturdiness of this little gadget. Also, it rounds of the corners NEATLY and COMPLETELY, something the old one from another company I had did not do. It also requires much less effort to punch. Add to this was the super fast time it got to me, even though I chose regular shipping.Update January 2016: I've been using this for almost two years (mostly on 140 lb. watercolor paper) and it's holding up well. I'd certainly buy this again.

It works!!! I have been able to cut through a couple if sheets of paper at one time. It doesn't take a huge chunk of the corner in the rounding process. No complaints.Wellll....a couple of weeks into it, I used it on chipboard and it jammed permanently....not so good any more...if all you use it on is paper and light weight card stick you should be okay. Mine is in the local land fill.

The corner cutter made nice clean rounded corners with no frays or tears. It very easily cut through a single layer of 80 lb cardstock. It also cut through two layers of cardstock, but required quite a bit of pressure to do so.

A must-have for all craft projects. Once I got this, I went around cutting the corners off of everything I could find. Something as simple as my child's drawing on the refrigerator got an instant upgrade with rounded corners. I bought this to make my own planner covers. Some cute scrapbook paper, a laminator and this corner rounder and you can change out your covers with the seasons. It's a big money saver. I wouldn't recommend doing more that a couple pages at a time depending on the thickness of the paper, though. It's perfect for personal projects, but may be a little lightweight for larger projects.

This does a great job of cutting corners. However, if you want to washi the edges of your cardstock and fold it to cut the center, good luck in getting it to fit.I'm making my own travelers notebook fillers, which is why I bought this. It makes those nice round edges. You can't do much more than 2 to 3 pages at a time which slows the process down. And I find if I washi the covers, I have less cutting by the elastic.
