I’ve been buying this for a couple years and it’s never let me down. It ships from the USA and I imagine the seller’s customer service would be good because of that, but I’ve never needed to call.This is my third order where they roll of paperIs crinkled and bent on the inner part of the role. Roll of ink paper is stuck to itself. Ripped on meTwice when I tried to pull it apart to install. Was able to work a way of using it. Needs some better quality inspection before it leaves. I have a box at home that is useless from being damaged, that’s how I received itFast shipping quality product very happyTwo orders including a replacement order and the product was warped. It is easier for me to buy on Amazon and have it shipped, but not worth it if you can't use it which was the case the last time with the replacement. I instead returned the defective product and ordered from a reputable supplier and had no issues, product was not warped. When you are a photo booth, your product matters as when you are out of paper, people are waiting and not sure what happened to this product as the previous year I ordered the product it was fine, but this year both times the product didn't have placeholders in the boxes for the center of the roll, etc... If you are going to buy this product through Amazon which I would not recommend, then buy two and you might get two good rolls or at least one good roll that will last you 400 prints. Not sure if this is an issue with the supplier or storage with Amazon, but it is the same price elsewhere and is not defective.Perfect since it is OEM.Great paper and looks great. Sometimes it's a pain to get going when you change out the paper but once it's set you don't have to touch it until the papers gone.Not much to say, this is standard DNP photo paper. If you have a DNP DS 40 and you want to make 4x6 prints this is what you should buy.Perfect for my printer
