I had to get a bigger set of nails. I got vet needles. Banded, got it numb, stuck the needles in, and slowly squeezed the blood out. It was exhilarating.
I just have 18G needles on order and will see how these work out
The ones I had were either 18 or 16. I also got saline to refill it. It was a big package of small pink tubes.
