A simple but well designed black plastic putting cup features a regulation sized 4.25\" (10.8 cm) hole molded into an incline ramp. The front of the ramp is flush with the ground and the back of the hole is about 5/8\" high (1.9 cm). The bottom of the cup has small protrusions that help keep the cup anchored on a textured surface like a putting green or low pile rug.
Basic cup makes a great target for indoor or outdoor putting. A great compliment to the Esoteric line of putting aids.
