I looking for a syringe with the 1/2 unit mark and the guy at Walgreens thinks I'm crazy . Looking on line this is what I'm finding for BD syringe in the purple box , are these the ones I need?
Also choose between 30 or 31 gauge (needle thickness), and short vs long needle.
I prefer 30 gauge as I seem to bend the 31 gauge too easily.
And the short needle seems to work better for me, too.
