Rotate the tag clockwise. A slight downward force should be applied.
You have 20 tags with unique markings. Match the appropriate tags with the golf club; ie the D tag screws into your driver. Only the "P" tag should be used with the putter.
There are 4 ‘spare’ tags marked X1, X2, X3 and X4, these should be used for clubs such as a 7 wood or a spare driver.
To remove the tags simply unscrew the tags (anti-clockwise) to remove them from your golf clubs.
