Copper Sulfate Smart Crystals are the perfect solution for eliminating filamentous or string algae.

        Maybe it will arrive. Or maybe not.
        Color: Gold
        Smells great, but never on time. This time I didn't receive at all, for what I needed.

        The answer to calloused feet.
        Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
        If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

        Slippery when wet!!!
        Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
        “These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”

        Love them
        Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
        I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again
