These are just what I wanted. They stay tied!! My last laces where were much thinner did not.

FWIW, "VERY thin" is what I'd call thin ... sortof thin ... on the thin side. But VERY thin seems to be the industry way of describing thin. It's like saying a drink at the theater is "large" when in fact it's humungus! It's not the right word, but I guess that's just the way the world is.
