BD Nano™ 2nd Gen Pen Needle, 4mm has a wider outer cover, easier to attach to your pen injection device, larger green inner needle shield is easier to grip and remove.
I love how these second gen needles are genuinly more damaging to the skin and leave huge welts over 50% of the time. Reddit threads show that these are the least popular needles ever made. Whats worse is that this has been going on for months and there has been no change made. Who asked you guys to change something that wasnt broke. These needles no matter the box, damage and tear my skin.
