These did an ok job. I'm a teacher so I do a lot of laminating, I have to say though, that I prefer the Apache brand sheets found here: https://www.amazon.com/gp/aw/d/B00NBCHTXK/ref=mp_s_a_1_10?ie=UTF8&qid=1497626492&sr=8-10&pi=AC_SX236_SY340_QL65&keywords=laminating+sheets&dpPl=1&dpID=51DBm%2BVDzHL&ref=plSrch You can see in my picture one of my classroom items I laminated and how it almost looks frosted in the corner, that's because you can actually open that edge up, many of my laminations happened this way but only with the Scotch brand. I got these when they had a lightening deal but would not purchase at full price
