This Hand Care Massager is very relaxing for your palm. The inflation air pressure does not last for a long time, just 2 seconds or so, in case your hands not circulate the blood, causing hand injury.
The massager-designed modes
rhythmically pressurize the whole hand starting from the wrist to the palms and fingers. Specifications:
