Here is a packet of those hard-to-find needles for your Singer 206, 306, 319, or 320 sewing machine. These are genuine Schmetz needles, made in Germany.
If you own one of these machines, it is important to use the correct needle to avoid damage to the bobbin case and ensure good stitch quality. The 206x13 needle has a shorter point than a 15-x1 "standard" needle. If you have any question about whether this is the correct needle for your machine, please contact me before purchase.
I also have Size 12 206x13 needles, Singer 206/306/319 bobbins, and bobbin cases.
Item will be shipped USPS First Class mail in the US.
