Plastic self-sealing bags perfect for making superstarch gels

We have had feedback from a customer saying that she found the black bag a bit small and as she was an open water swimmer she thought different size bags would be better. So as a result we are now offering different size bags. 

The small black bags are a thicker plastic and may not be the best for the plain superstarch. Plain settles out a lot more than the flavours, so may need remixing if stored. This will be easier in the medium than the small.

The large bag could be rolled up to put in pockets or slipped in to swim suits.
