frank green's newest accessory - the duo lid pack. 

Featuring one push button lid + one straw lid plus a strap and 170mm straw [for 20oz or 34oz bottles]. 

This accessory pack is great for replacing missing or broken parts, or if you just want to spice up your current drink bottle or coffee cup with different colour combos.
