Tanner Tees Batting Tee

Used outdoors for about 4 years, there is some deterioration, but it is in perfect working condition.

From the sales site:
Tanner Tees are designed to provide a realistic hitting sensation when striking a ball, as the most crucial part, the tip, is hand-formed into a flexible rubber roll (Flextop). This is the ultimate batting practice tool. The tee and base are detachable for convenient portability. The base corners are rounded for player safety. The tee part is made of metal, making it more durable and resistant to rigorous practice compared to many commercially available plastic products. It is the No. 1 trusted batting tee, favored by high schools, universities, and all Major League Baseball teams. It is also ideal for softball practice.
Height is adjustable from approximately 66-110cm, recommended for ages 9 and up. Suitable for a wide range of ages, from children to adults.
