I bought this to make headphones. I prefer TPU for its flexibility. This makes the headphones more durable and comfortable to wear. This thread is perfect for that purpose. It was less orange-red than other red threads I found. I have a direct feed printer so it was easy enough to work with. The earbuds are durable and flexible. I'll definitely get more if needed. (I was offered a $3 gift certificate in exchange for an honest review. This did not affect my rating in any way.
