Product review (1 stars): This is NOT SPT-1 wire!!!
Like another reviewer has stated (and I wish I had heeded his 1 star review before ordering) this cord is SPT-2 wire, NOT the advertised SPT-1 wire! I am trying to repair a small, very delicate lamp which requires an inline switch and this wire insulation is much too thick to work in such a switch. Avoid this product if you truly need a thin SPT-1 wire!
