The box I was sent felt like it weighed 20 pounds. In the box, there were a ton of award winning, classic, hard cover books. I was also given Apples to Apples for kids, along with other great games that will keep my class busy during free time and indoor recess. This amazing company supplied my classroom with activities that I would never be able to dream of affording, and I am forever grateful to them. Wish I knew the sender's reddit username, so I could give them all of the public credit they deserve!
