So we might also stock some PET bottles as well. If you guys could choose any PET bottle size to use with this cap what size would you choose? We could make any size from 1L up to 5L. The bottle cost would not be very high. Only a few dollars per bottle. The increase in size would not have a significant increase in price. So to get your feedback what size would you guys prefer?
I would say definately a 5L option, and possibly a 1 or 1.5L for taking a couple to a BBQ or similar
