Thought my Paper was horrible!
Size: 11"X17"
beautiful glossy paper I purchased 110 paper from staples thinking this was going to be thinner when I received it was way thicker then staples paper was totally impressed very cardboard hard like paper, my only down fall is that I have the new inkjet printer from Brother and it never drys overtime I touch the print it comes off on my finger giving my pictures finger print's so I hav to send it back so a wonderful verified user text me and told me that I needed to change my printer to glossy setting again my printer is very new now my Koala glossy paper works amazing so its basically the best glossy paper I have ever seen and used. so I am giving this view my first 5 star rating that I have ever giving for me thats alot!

Great for Indy Comic and Zine Covers
Size: 11"X17"
I use both the 11x17 and 8.5x11 Koala Glossy Inkjet papers as cover stock for Night Phoenix Press mini comics and zines, most often as Kickstarter add-ons or promo items. For that role, they deliver. The gloss finish immediately gives even short-run projects a polished, professional look with the other side having a matte finish which I can flip over for sketch covers using the matte side for the exterior cover. Colors print vibrant, blacks are strong, and the surface takes ink evenly without streaking. The finish looks clean enough to pass for offset printing on both inkjet and laser printers. This paper is also great for comic covers because it can fold down the middle without splitting the gloss coating too much if at all. The 8.5x11.5 works just as well for minis, one-shot zines or inserts. Between the two sizes, I can cover nearly every indie project format I need. They have just enough weight to feel like a true cover while still running smoothly through an inkjet printer. These books are often handled by backers or used as handouts, so durability matters. The stock holds up, though glossy paper can pick up fingerprints or light scuffs if stacked loosely. Bagging finished copies or boxing them quickly solves that. For the cost, it’s a dependable option that makes Kickstarter rewards and promo zines look far more professional than plain paper covers. For creators producing indie comics, add-ons, or zines on a budget, this paper is one of the easiest ways to elevate presentation without driving up printing costs. -Nathyn Brendan Masters

Ausurion products protection
Asurion is a great company to insure your products whenever you purchase items from online businesses like, Amazon. I had a portable hot spot device ordering from Amazon with a 3-year protection plan, unfortunately, the device has accidentally fallen and refused to turn on, then I went on Asurion Online website and filled in a claim and waited for approval to take that device for repair, luckily, they do not haven’t repaired shop services near me, they just refunded the original item price to me by Amazon Gift cards without knowing it few days than expected. I highly recommend Asurion for your product insurance needs.

Assuring takes care of their customers.
Asurion was the best purchase you can have when buying electronics. We purchased a HP printer, which we have always had excellent luck with, but this one was a lemon from the beginning. We called Asurion and they immediately took care of the problem. Thank you.
