Vanntett tape

Used a piece of this to keep my kids’ bandages dry during bath time, and not a single drop got through. The adhesive stayed put even after some serious splashing, and the roll is plenty long for the price.

Finally changed out the dressing on my knee without the edges curling up—this tape stayed put for three days straight, even through a couple of showers. The roll’s a solid deal for the size, and it peeled off cleanly without leaving sticky residue. Just what my first-aid kit was missing.

The adhesive on this roll is seriously strong—it stayed put through three days of showers without peeling at the edges, which surprised me. Feels economical too, since a little strip goes a long way for securing dressings.
