Nice paper, badly packed for delivery
Size: 800 Sheets (24lb), Size: 800 Sheets (24lb)
The paper is good, the price is decent, but they threw this oversize "ream" in a box and let it bounce around. The box was about an inch or two larger in all three dimensions than the paper, and they didn't put any packing paper in the box to hold it in place. The paper itself arrived mostly undamaged but the wrapper was destroyed. Since most of the paper was OK, I didn't want to make an issue out of it with Amazon and send it back, and risk having another "ream" arrive in even worse condition.

Very Good Paper for Everyday Personal and Business Use
Size: 1500 Sheets (24lb)
I have purchased these 3 packs of this 24lb letter-sized paper several times. It is just fine for everyday usage and I have no problem with it in my Canon B&W and Color laser printers. Print quality is good and sharp. This is much better than the fairly flimsy 20lb and is very suitable for ordinary business usage. It also works quite well for two-sided printing as the back side does not show through. But it is not 28lb+ manuscript quality and should not be expected to be.

My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches.
I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces.
If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.

Best Sublimation Paper
Size: 8.5"x11"
I’ve been using A-Sub paper for my sublimation projects, and it is easily one of the best. The ink dries almost instantly once printed, so I don’t have to worry about smudging the design or getting those annoying "pizza wheel" marks from the printer rollers. The paper itself feels substantial and doesn't tear or curl easily. One of the biggest wins for me is that it never jams; it feeds through perfectly every time, saving me the frustration of wasting expensive ink and paper.
When I go to press my designs, the ink releases almost completely, leaving very little behind on the paper and putting all that color onto the project. The final results look super professional, with colors that are vibrant and sharp rather than looking faded or dull. It has worked perfectly for everything I’ve tried so far, and if you want a reliable paper that gives you consistent, high-quality results, this is definitely the one to get.
