Left Product Name: White Copy S 500 sheets, but it looks like there are over 400 sheets remaining. Right Product Name: Konica Minolta Multi OA Plain Paper 250 sheets, but there are a little over 100 sheets. I used these for reports in my student days, but I no longer need them, so I'm selling them. Both were stored in a dark place, so there is no discoloration of the paper. Instant purchase is welcome. Both sizes are A4. If you only want one, please comment.
