High quality, easy needle combo
I have a Sterling pen digital machine, and these combo needles with casing are the best since are 'all in one'. I ordered a #5 round, but really wish the #4 round (green casing), would be better stocked, since I am used to using the #4 and like that combo best.

Awesome service
My products were packaged well and sent on time. I love working with these needles, they are smooth function and less vibration...fabulous!
