    • Wanted a 4mm but this worked the same
Size: 1cc-31G 1/4" Number of Items: 20
I searched for a 4mm needle but this one worked perfectly. The unit numbers are large, the needle is fine and was completely painless. The plunger is a tad bit hard but was perfect for my need.

    • Excellent
Size: 1cc-31G 1/4" Number of Items: 100
The issue with no name syringes and needles is the sharpness is always hit and miss, even in the same box. These have been consistently sharp and painless every time and I'm disappointed this seller is no longer selling the size I need. Having dealt with inconsistent sharpness with other one I will probably order name brand for my next box since I can no longer get these ... show more
