With this specific product, I remove not only calluses but also hardened skin on my feet. Depending on how tough the skin is, one or two patches will be needed, for two days each. If it is on the sole, it may require extra fixation with adhesive tape to stay in place. With a foot bath afterwards, everything comes off.

It does the job well. Simply, if the adhesive is good on the sole, it is better to secure it with additional adhesive tape for safety, so that it does not come off quickly from friction

It comes off very easily...if you wear it for even just an hour, you have to replace it...so the 8 pieces are few since you will break 5-6 each time.

I bought them for the first time, until now I was buying from another well-known company. They are equally high-quality and effective. The price for the quantity is very good! I recommend them. It takes a few days to remove the calluses and possibly a couple of changes.
