I purchase these because it states Covidien Monoject as the brand. Instead I received CardinalHealth Monoject needles, which are not the same. I really like the Covidien Monoject brand much better than what I received. Not sure what happened, but it is frustrating.

When will they be back in stock?

These syringes were way better quality than the ones I have to use now. They have been out of stock for a long time.

Our puppy handles them well

We like this size syringe to give our older dog insulin. It is easier for her to tolerate since she needs 2 injections per day.
