Sub for discontinued BD Nano pen needles?

Hi, Just learning that BD320550 (“2nd Gen”) is discontinued, and the replacement my pharmacy supplied (BD 320122 “Ultra-Fine”) has a pokey looking nub at the base of the needle. Has anyone tried the Ultra fine with the extra nub? Does anyone know if there’s another brand more similar to the 2nd Gen?

Hi Emily @emilyok! I have used BD “ultra fine” pen needles and they were fine! I didn’t notice the pokey nub, but I was under the assumption that they were like all of the other pen needles and didn’t really look at them.
