Button knife / beverage film / straw bag accessories

Considering that it is not easy to find a flat table outside, slowly tearing the beverage film, It is not recommended to directly puncture the film with a straw glass pipe (our pipette group is equipped with a flat mouth pipette. If it is dropped, the force is relatively uniform and it is not easy to be cornered). We have developed a button knife that can "snap" the film and hang it behind the straw bag. Before use: Please use utensil cleaner to clean > Dry > buckle to the straw bag "back belt" How to use: Open the button > Remove the knife from the straw bag > Puncture the beverage seal from top to bottom > Put in the glass straw > Hang the button knife back into the straw bag PS This knife is not suitable for "cutting". Please use the "puncture" method, it will be more convenient! The knife is made of PP plate and uses Japanese Kiyohara baby clothes button (tested by OEKO-TEX® Standard 100 hazardous substances)
