Platypus Closure Cap (pack of two)

Quintessentially pertinent in it's usefulness; the water of life is encased until needed and can then flow as pearl like droplets into the chosen receptacle.

I wanted to take my plat on an expedition for extra water on the second day, but I only had the tube to go with it. The cap came in very handy for this exact purpose.

Very thin plastic

It works, end of really!

Ridiculous price - recycle lemonade tops that fit
