They fit my henry schenier lancet pen perfectly. These lancets are good quality, work very well.

Lancing device works great, has adjustable forces. Thanks goodness for google. Amazon is my lifeline!

I'll be discarding these and looking for a new brand. They are too short, floppy and sometimes eject when that is not what you had in mind.

The lancets are fine but i despise the lancing device. It is extremely difficult to eject the used lancet from the device. When triggered the point isn't within a quarter inch of protruding.
