Recently for the last 2 weeks, we have noticed a change in the caps on the HEB Tonic Water. We are unable to remove them without a tool from the tool box. When removed we replace it from a bottle we had previously. Actually maybe this is a total redesign of the bottle now that I think of it, but it does no work for us. Please do a test for yourselves with HEB Tonic Water. User's recommendation: Go back to the fromer bottle cap design.
