I ordered two from Kent Wang and am thoroughly satisfied.In case you're still looking for a grenadine tie: I can also recommend Elizabetta (https://elizabetta.net), who sells excellent lined grenadine ties (including multiple shades of navy blue ones). They are lined with wool and tipped with silk. Shibumi's are also nice but are unlined. I guess it's a question of taste what you prefer .
I saw the brand you post of but always a bit skeptical of Amazon brands.
