In order to release fish in the same condition as before the bite, if not in better condition, we created the Ulcer Swab liquid. Many products available on the market are designed to treat injuries caused by hooks, but this variant is perfect for abrasions, ulcers, and other injuries on the rest of the fish's body. Ulcer Swab was specifically developed to clean and disinfect these areas, preventing infection by fungi and bacteria, and then to seal them with Propolis. Each vial contains 30 ml of product and is equipped with a dropper dispenser.
