Replacement adhesive strips for the wall-mounted holders, cut to the footprint of each model — so a move, a repaint or a new wall does not end the life of a dispenser.

A replacement adhesive strip cut for the 4-cup wall holders — same bond, sized for the wider family panel.
The adhesive is the part of a wall-mounted holder that does the actual work, and it is also the only part with a reason to be replaced. People move. People repaint. A set that lived happily on tile for two years comes down and needs to go up again on drywall in a new flat. Throwing away a working dispenser because the back of it is no longer sticky is a bad trade, so the strips are sold on their own.
They are cut to footprint rather than sold as a generic roll: one shape for the 3-cup holders, one for the 4-cup, one for the sanitizer stations. Clean and dry the wall, press firmly, and leave it to cure before anything is hung on it — the bond needs hours, not minutes, and that wait is the whole difference between a holder that stays up and one that does not.
