They stick to the skin without causing irritation and come off easily. I would like the inner gauze to be thicker.

They are placed approximately at the height of the sides, on the sides. They come off, if not immediately, within a short time, especially as I move my torso. I have tried other more expensive ones that do not come off from the skin at all, but they left redness/rashes after a few days of daily use. So for a few days of use, it's better to go for something more expensive, but for many days, there might be an intermediate solution that I haven't found yet.

The quality of their construction is not perfect, but they are worth their money and worth being in your pharmacy
