Yes, these tees are approved by the USGA and R and A. So perfectly legal for use in all competitions.
The USGA updates its list of conforming balls the first of every month. Balls are added and balls are removed. The balls on the list for any given month are the only balls allowed to be used during a USGA sanctioned event for that month. Not long ago the FUZZ ball, which had the "wicked long, wicked straight " seam markings were USGA approved. The current ball, which changed the seam markings to "wicked long, super soft" is not on the current list as of October 2012. RG Naples and Cape Cod
