Would this fit on the 12 oz kids Hydro Flask?
Is there a straw cap for the 25oz wine bottle?
Will this top fit the 25 oz wine bottle flask?
Will this one fit on the 12oz kids one? I have ordered one for her and she keeps coming home from school and it leaks all over her backpack.
Will this fit an 18oz hydro flask? If not, is there a lid for an 18oz like this?
I lost my old cap from the bottle bought back in 2015. Does this fit the old 21 oz standard bottles?
Will this cap fit 25 oz Wine Bottle?
Our 21 oz, insulated flasks are our favs but over time, water got into the caps and the standard rubber ring developed mold. Took it apart & cleaned it, but the seal is discolored & water is difficult to remove from cap. Will new design solve this?
