You need to have half unit marks on the syringes in order to be able to get all the dose fractions that you might want to use. From what I can see, these only have whole units. If you repost this thread with a question mark icon in front of its title, it'll attract more immediate attention. There are many who order from ADW on here and they can advise you about syringes with half unit marks. I'm in Canada and I buy mine from my vet.
They're also available at WalMart if you have one near you..Their Relion Brand 3/10ml, 3o or 31 gauge, 8mm insulin syringes all come with half unit markings and are only $12.58 for a box of 100 (although it seems a lot of WalMart employees don't realize that they DO come with half unit markings!!)
