I've some some of the Therapak canisters. How are you removing the labels? About the best method I've found is sand them off. It would be nice to find a solvent that didn't damage the container.
Well, I'm a couple of days late, but Merry Christmas and espeacilly Happy New Year to you and yours.
By the way, I really need to call you about a new pokey stick... Mine is 'near bout wore out from all the trail hikes the past year
