This is very convenient. You discard your old needles in the top where they cannot poke you or cause a mess, and you get new needles from the bottom. So it eliminates disposal and storage problems and keeps your supplies organized.
I got the package quickly and the syringes work perfectly. The dog doesn't seem to mind when I inject the insulin. It makes it so easy to give her the doses twice a day. The dispenser is perfect for disposing the used needles.
