If you’re consistent with the right amount of a material in each bag. And you have the temperature set properly. These bags work perfectly and flow consistently without leaving Rozen in the corners. I check the ratio of product versus yield and every time I’m on the high end. They are a little tricky folding the corners in but once you find the trick, it’s consistent and easy to do. I highly recommend using these bags. I’ve re-ordered many times love them.
Good product, good stitching. Never had any blowouts.
