I'm switching from mini pen needles, which are 5mm and 31G, to nano pen needles, which are 4mm and 32G.

As a math teacher, I was really struck and not at all happy to see the major mathematical error on the back of the Nano needles' box. It has a picture comparing a Nano needle to a short needle. The caption says "BD Ultra-Fine Nano is 50% shorter & 8% thinner!" and underneath, written on the pictures of the needles, it says 4mm² an 8mm² on the green one. But the dimension being described is length, not area. The difference is between 4mm and 8mm, not mm². This is a crucial difference.

The opticlick Lantus pen cartridges have been discontinued, so the pharmacy called my doctor and asked for a prescription for a different form of Lantus. I expected to get vials, but to my surprise I got these Solostar disposable pens:

Unfortunately, although I wanted syringes with half unit increment markings, I once again got the ones with whole units. The box with the half unit increment markings is from almost a year ago.

I love that you checked out the "math"!
And...on the plug incident with Joe's site...I actually thought of the needle part after. The plug does not have a needle, but chewing off the connector did leave us with a pseudo plug with the needle...not sure if that was a good idea. I secured a IV 3000 over the site...but still, it could have been compromised by the entrance created by the needle I suppose.
