Unlike the loose and slippery cuffs of ordinary gloves, the “safety mouth” design of this glove is the first solid line of defense for protection.The cuffs are made of high-elastic knitting technology and are equipped with a tightening locking structure, which can closely fit the curve of the wrist and the tightness is just right-neither will it compress the blood vessels of the wrist due to excessive tightness, causing numbness in the hands; nor will it be displaced during activities due to excessive looseness, allowing oil, dust, and sewage to enter while it is empty.In the car beauty scene, when the staff wipes the body and cleans the wheels, their arms are waved frequently, and the safety port can firmly fix the position of the gloves to prevent car wash liquid and oil from seeping from the cuffs; during deep cleaning of the home, clean the range hood and wipe the gaps in the tiles. Even if the hands are repeatedly pressed, the safety port can block the invasion of detergent residues and dirt, and keep the hands dry and clean.It is also worth mentioning that the edge of the safety mouth is brushed and soft to the touch. Long-term wear will not cause friction damage to the wrist skin, making the protection more user-friendly.
