Designed to cushion the bottom of cylinders while pumping as well as provides a better seal at any pressure. Especially good for folks with heavy pubic hair who do not want to trim for pumping. Made of high quality silicone.
Silicone is hypoallergenic, hygienic, and durable. To clean, wash with soap and water. Toys without electrical components can be cleaned by boiling for 3 minutes or on the top rack of your dishwasher with no detergent. Silicone toys should not be used with silicone lube.
