A handy kit!

One of the things I most love about b.box cups is these replacement straws. Whenever a straw gets discoloured, chewed on too much or just a bit grotty, it is so easy to replace it. We always keep at least one spare on hand in our house and the cleaning rod is a great tool for washing up too.

Great kit

You NEED this if you use the b.box sippy cup, no doubt about it! The straw gets moldy every few days, and don't forget to use the little brush to clean up around the plastic seal of the lid.

Love this product...but

I love that I can clean and swap the straws around. However, I did break one of the straws when taking it out.
