The black top stoppers feel a little tougher than what I’ve used in the past, which may dull the needle and that could be causing some irritation but I doubt it.I’m a pin cushion with the Test C 250. I haven’t had any PIP with the old green tops or the new black tops. 29g 1/2” insulin pins most of the time but I’ve loaded up the 3ml with a 25g before traveling and still no PIP.
