If a plain white envelope containing anything odd shaped other should go through a sorting machine it will arrive at destination with nothing in it. I made this mistake a long time ago with 3 tiny chrome screws. What you are expecting is a poke a hole / feck something up part.
Still waiting for the repair bill on the sorting machine. Can you imagine being the mechanic there, scratching your head, wondering where these extra little parts belong ?
I'm sure someone will chime in here with, " All you need to do is bend this little thingy".
ROFL Good luck
p.s. I could send you the part and if it needs painted I do have the correct paint. I would properly package the thing so it gets there too so the total would be a dozen dollars.
