Staples Copy Paper -- Item # 135855 Product quality has declined to a grossly unacceptable point within the last year. Individual sheets are now so thin my laser printer grabs several at once. I have a stack of wasted blank sheets that have gone through the printer and are now too curled to be used a second time. I typically lose 10% of every case to waste due to the poor quality of this now near-tissue-paper-thin product. Definitely not worth close to $50 per case. Cannot recommend this paper for laser printers. I will be switching to another brand.
