One-time protective cover for backpack, thin, I don't think I can use it again.
A one-time check, not too thick, I don't think it's gonna work again.
Got it. I don't know how long enough. Let's hope for the best.
I bought a bag that's not so dirty and ready for security.
It's cheap, but it's useless.
It's been used once. It's practical.
It's a good idea.
