Coralife Aqua Gloves are full-arm length with elastic bands to hold them snugly on the upper arm. The gloves measure 28" in total length and are made of the finest PVC material with fiber-reinforced sleeves. The Aqua Gloves are designed to allow the hobbyist to work efficiently inside the aquarium without contaminating the water. The gloves keep arms and hands completely dry, thus avoiding any possibility of skin contact with the water and its inhabitants, which prevents stings and allergic reactions.
