the main reason why i want to return the colcasac is the fact that since its so snug which i like but kinda hate , since every morning i have to spend time to put it into this sleeve which takes a while and then if i want to stop at the library in-between classes or something , its a pain to take it out of the sleeve , so the main reason is the inconvenience it provides , so if it provides no protection i might as well return the sleeve and get $30
