Grinding hard objects to be crushed, such as ice cubes, nuts, biscuits, etc. Wrap it in a fresh-keeping bag and crush it with a rolling pin. It's quick and easy to use. When you go to the seaside to play with your mobile phone, cover it with a fresh-keeping bag, so you don't have to worry about the water in your mobile phone. It is difficult to clean the fixed shower head, so it can be tied to the shower head with fresh-keeping bag water. Drop the washing liquid into the water and it will be absorbed quickly in the shower.
