Quality prints, this is what ‘matte’ should be
Size: 8.5"x11"
Really nice results and the double sided coating eliminated the worry about which side to put down in the printer. Value seems fair, quality is very good, color is excellent, dried quickly, nice thick paper. I use an Epson-3750 printer with it and it did initially have a hard time grasping the sheets so make sure to fan the paper first.

The paper looks great, and for the price it's awesome!
Size: 8.5"x11"
I took on a job of a couple who wanted some wedding invitations printed. Originally they wanted matte paper, double-sided, just the basic stuff. I printed out a sample of course, and then printed out a few more samples on different finishes just to make sure they got what they actually wanted. Turns out, they really liked a luster finish! Great! Except I had no double-sided luster paper. Well, quick trip to ol' faithful Amazon, and found this when looking for double-sided luster paper. It looked promising, and the quick turnaround of Prime meant if it didn't work out, then I could reach out and get some more expensive stuff instead. Luckily, I printed using the Premium Luster inkjet preset on my printer, and I was blown away by the print! It doesn't have the highest detail retention of all the papers I've seen, but for a heavier stock paper, this stuff worked out great! The thickness is just right, and it went through my printer perfectly. For the price, this is an excellent set of paper, and I do not regret the purchase in the slightest.

Amazing Paper
Size: 13"x19"
My favorite paper to use - great quality, has a shimmery feel, and the prints did not waiver when accidentally in contact with a small amount of water overall. This is my go-to!

Good for last minute poster printing
Size: 13"x19"
I’m a full-time artist and I ordered these to make some last minute prints for a convention. For the cost, they do the job. The finish is decent with some imperfections if you look closely but overall can’t complain. If you’re not super worried about the actual paper quality while still wanting a good looking product, I’d recommend.

Fantastic for Greeting Cards using inserted photos!
Size: 8.5"x11"
Great for making Greeting Cards with your inserted photos. No more smeared ink on cards. Makes Fantastic Cards, everything justs pops out with vibrant colors. Plus are also heavy enough. Love it
