These bags are the BEST for storing individual pieces, gameboards and instructions for math games for work centers. We laminated the instruction page and used packing tape to attach it to the outside of the bag. These bags are very durable - many hands over the past 2 years and no rips, tears, or broken handles. We bought the storage rack to use with the bags and keep the games accessible for the children.
I have been using these bags for over 10 years for our books with cassettes and now books with CDs and we love them. They are durable enough for everyday use and keep books together with their cd very nicely.
