I'mr really excited to have these nice cardboard sheets to use for arts and crafts in my preschool classroom. They are a great size and perfect thickness for my use case.

I'm adding these around the inside of shipping boxes, particulalry for wide and long boxes that are short (like 22x16x4). These boxes seem to be crushed more often during shipping and adding the cardboard sheets vertically along each side adds a good amount of strength. They are sturdy, but not too thick or heavy, so they don't add much weight to packages.I ship collectables, among other things, and the product packaging condition is important. The cardboard inserts noticably add to my material cost, but I think it's worth it for valuable and/or delicate items. Also, my customers specifically mention packaging in their reviews, so it does postively impact the customer experience.These are useful for other tasks also. I've used them as a backer when trimming something with a razor knife and to help get a deeper impression from tracing wheels. I'm sure there are a hundred other uses too.I'm happy with these cardboard inserts and would recommend them.
