The Yomiuri Shimbun“Lift Tee Spiral”
These golf tees can be adjusted for height down to the millimeter. The desired height can be locked in place so even after a user strikes a ball, the tees do not need to be readjusted. The bottom point of the tees are shaped in a way that makes them easier to penetrate hardened soil in winter. Each pack contains seven tees. Three size varieties are available.
