Callaway club number tags. Used for UT and FW. The second photo is the back side of the first photo, with the same arrangement. The chips marked 2D/3D/5D did not fit on the three tag heads. They seem to be slightly different in thickness. I think they would fit if you add some thickness to the base with cellophane tape, etc. The white Callaway mark has some dirt in the hole for the string, so please consider it as a bonus. Thank you for your understanding of the condition.
