One Touch, they’re very expensive,like,about 8e for 2, so I decided to look for a cheaper options, so I ordered accupntuer needles, I got 100 for 8€ they fit perfectly into the shank of the One Touch…problem is, the ones I ordered are not as slender as the one touch needles!..
I’m going to re-order the most slender ones are see how they work…
