ok. 10lbs is a an exaggeration but they weigh about 5 pounds each and they take up a lot of space in my bag and with binders and such. but if i just put in 2 textbooks,1) no space left in bag,2) feels like it weighs a ton and in its current condition, my bad is gonna rip if i put that much strain on it. LOL as far as weight goes, not too good at guessing weight. checked on amazon for the weight. about 5 lbs.
