Reviews for Clever Choice Comfort EZTM Insulin Pen Needles 31G 6mm (1/4 Inch) - 100 Count
People say Clever Choice is really similar to Novo Nordisk.
They work perfectly
I tried one of these out with a Levemir brand Flexpen. It worked perfectly in all ways and, at about 50% less than the Novo Nordisk brand I have been using, I will continue to purchase these from now on.
