I have the 3/8 tip on the new iron I have, the X-30, and it is the one for small goats, not the 1/4 size for Pygmys. I need that 1/2 tip for the size kids I have. This one would work for Pygmys or Nigerians. It isn't the Pygmy size though, which would be, I guess, too small for anything. . .unless you're disbudding rabbits. It is brand new in the box. I either need to sell it - if anyone is interested, let me know - it was $59 - I'd take $45 and ship it, too. . . or I need to find out if I can replace the tip with the 1/2. I can't tell if this tip comes off and can be changed out. Thought someone here might know.
