Review on 📀 Maxell 190134 CD & DVD Paper Storage Envelope Sleeves - 50 Pack with Clear Plastic Windows (Multi-Color) - Great for Organizing your Disc Collection! by Kuldip Roberts

The Amazon listing says the paper is heavy duty paper but the paper they are made from is not heavy duty or what does that mean. It just feels like regular paper and is pretty thin. The box I received is white, not the multicolored box as shown in the Amazon listing, but corresponds to #190132. (At first I thought the wrong box might have been sent) No where on the box that I received said "Heavy Duty". I'm not returning them because they were such a low price and they are used to gift the CD/DVD to other people who will hopefully supply the discs in a more appropriate holder. If you're looking for "heavy" paper CD/DVD cases, you haven't come to the right place.
