Rubber ball suction
Traditionally, heat is used to expand the air inside the cups, creating suction, but many cups today use suction balls and valves instead. This allows for easy suction adjustment and negates the requirement for heat, which can make some patients uncomfortable.
High-quality materials
The glass used in suction cups is extremely hard-wearing, durable and easy to sterilise. You can remove the suction bulb easily to wash separately.
