The b.box replacement straw pack supplies two straws for the new-style b.box sippy cup, along with one weighted steel ball and a cleaning brush. The straws fit the new cup only: they do not fit the older glossy sippy cup, and old straws do not fit the new matte lids. The new lid remains compatible with the current base. Dishwasher safe.
