Cool Hunt !

Hello, I really appreciate your effort & Here is my opinion-

Well, Not only toilet paper but usually we waste so many Papers in the Class and As a Computer science I tell my Classmates as well as teacher to don't ask for hand written Assignments instead of we can give you Word file. I know it is not a big thing but small small steps can be a massive change.
This is pretty cool technology that could be implemented in order to save Environment and it looks luxurious too.

Thank You & Happy Hunting :-)
