FS: 62mm B+W MRC polarizing filter

hello,

I have a B+W 62mm polarizing filter for sale. I have the box and it hasn't been used much (on two holiday trips), no scratch.

This is a high-end filter...

here is the current google shopping price:

Make offers!

Would prefer collection in London but can post if needed.
thanks

P.S: I can take pictures of it if needed although a filter is a filter!
