With the comfortable shape of a neoprene ballstretcher - but made of soft, stretchy silicone - the Neo Angle's width is graduated, so that the longer end pushes your balls forward.
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.
