I recently switched from using Stomahesive to Eakin seals, and I like the Eakin much better. It's thicker and protects the skin around my stoma so much better. The one I've been using comes in a strip that you mold around the
opening of the wafer, so it's not in a tube. You might want to order some and give them a try before your trip. If you like them, you can carry one in your hand luggage without having to worry about
having a tube of Stomahesive with you.
I saw that you recently returned to work. Congratulations! How's it going?
