Great product have used them in small kids reusable juice box straws camelback eddie for kids and adults the mouth piece and the straw bubba straws smoothie straws have not had a problem with any of them

A trying to be ecologically minded by using ball canning jars with their sip and straw lids but could not find a brush to clean the smoothie size straws

Exactly what i was looking for to clean sports straws and hydro flask straws

I feel better using the bubba straws after cleaning them well with the brush
