Donut / cup coat


Donut is a protective cover for paper cups. It will transform into your private security guard instantly after attaching it onto a paper cup: you can use its front end to push the outlet switch of the drinking machine when you want to collect water, so that your cup mouth will avoid contacting the switch directly; the pushing strength will act on Donut instead of the paper cup, so that the paper cup will not get deformed and cause bad experiences; the side of Donut is designed according to ergonomics, which is more convenient for you to hold
