Works like a small piggy bank for disposed blades. Thankfully my main color of choice is teal, I believe other customers would be glad to get a tin that matches their razor. I also wished there was a way to fully close the slit, in case one travels or moves, to avoid potential spillage, but maybe taping would be enough. I don't think I'll recycle the whole tin though, seems like a waste of material and money (to buy a new tin) - I would rather transfer the blades into an already used metal can, ready for recycling.
