These work fine for my DYMO 4XL. Have printed thousands of labels. Note that you can’t use the 1st label because it spits it out as a blank when you first load the roll. You also sometimes can’t use the last label as it may be flawed. And even if you can use it, the next roll prints a duplicate of it. So basically you can’t use 2 of the labels from each roll.. it’s not 220 per roll, it’s 218. Very rarely (maybe 1 in thousands) does it spit out blanks in the middle of the roll but I have seen it happen because there’s no hole to tell the machine to stop.- These stick fine on kraft rigid mailers and boxes.- I have been buying these for over a year and a half, purchased 17 times as of today, buying 6-12 rolls per order.- I appreciate the free “Handle with care” stickers they include with each box, and how tightly they package the box so no rolls are damaged upon arrival.- I have not researched if there are cheaper, better labels out there because I don’t have time.. these are always in my order history so it’s just easier for me to add to cart. I’ll continue to reorder these as long as the quality stays the same.
