I ordered a similar style pair a while ago and have worn them some - let me look up what brand they were.
OK, I got mine via The Grommet and they were Key Socks brand. I'd say they are pretty nice and as described. The Grommet still carries them too - a two pack for $24: https://www.thegrommet.com/key.....y-keysocks
The reason I haven't worn mine too much is that they are "one size fits all" and I wear a size 10; they're a bit snug on me. The 'no show' aspect works well in the front, but it does show a bit on the back of the heel (achilles tendon area) if you are wearing slightly shorter pants, especially when you sit and your pants naturally come up a bit as your knee bends. If you want 100% no-show ever you'd probably be disappointed, but as long as you're wearing full-length pants and normally shaped ballet flats or heels, they won't show when you're standing.
