A golf tee may comprise an upper portion, a lower portion, a hinge, and a magnetic coupler. The hinge may be coupled to the upper portion and the lower portion and enables rotation between the upper portion and the lower portion only about a single axis. The magnetic coupler may be coupled to the upper portion and the lower portion and releasably maintains axial alignment between the upper potion and the lower portion by magnetic force.

An adjustable golf tee comprises a body extending from a head, a plurality of bulbous portions extending radially from the body and spaced apart along a length of the body, and a flexible stop adjustably secured to the body between an adjacent pair of the plurality of bulbous portions. The flexible stop comprises a disc defining a central hole through which the body is configured to pass to releasably connect the flexible stop to the body.

The golf tee marking device can place a notch in a golf tee multiple times and at multiple heights, one height for drivers and another height for irons. The golf tee marking device comprising a housing for inserting and holding a golf tee, at least one lever having means for crimping said golf tee within said housing, when said lever is activated. Wherein said golf tee is positioned in said housing and said lever is activated by a user, said crimping means creates a notch on said golf tee to the correct height of the golf tee.

An indoor golf tee includes a tee base and a tee shaft. The tee base has a base top portion and a base bottom portion. The base top portion has a connecting hole therethrough. The tee shaft has a shaft top portion, a shaft bottom portion, and a shaft body. The shaft body is connected between the shaft bottom portion and the shaft top portion. The shaft top portion is configured to hold a golf ball thereon. The shaft bottom portion is removably connected in the connecting hole of the tee base in a perpendicular orientation to the tee base. When the base bottom portion of the tee base is positioned on a surface, and the shaft bottom portion is connected in the connecting hole of the base top portion, the tee base orients the tee shaft in the perpendicular orientation to the surface.
