So here's the truth about Inspira needles. When SVP - the parent company that owns Singer, (husqvarna) Viking & Pfaff (& white) - bought Singer -- the singer "name" was/is owned by another company that is in no way, shape or form connected to the Singer sewing products that we all know & love from the USA. The Singer name has been sold - over & over. Current SINGER machines have ABSOLUTELY ZERO connection to the original company. Because a different company owns the singer NAME for the notions end of the business, SVP could not continue to sell the needles as "singer" so SVP created the name "Inspira". Inspira needles are standard household sewing machine needles with a flat back & will work just fine with 99% of domestic household sewing machines. They are similar to Schmetz, Organ, Kassel, or any other brand. If you want authentic "singer" needles (for whatever reason) choose Inspira. This is info given to me from SVP
