The tie clip certainly looks unique, but the quality is disgusting. It is very loose and arrived with a gap of about 3/16 inch. Unless your ties and shirts are very (very) thick, this clip will often come loose and slip off. Don't waste money.
Pros
He came on time, proved stronger than expected. Will take a long time.
Cons
I love Howson tie clips but am very disappointed in the quality of this clip.
