16t dmr single speed cog

Hi here I have my 16 tooth dmr single speed cog, I purchased it in a set but also purchased a smaller cog at the same time as the set so this one has been sat in my room for about 5 months unused and untouched, it has been on a shelf covered by a book so I only just found it

£5+£1 postage

Nothing really special but its dmr so it will last 
Any questions or if you want more pictures just pm me

Thanks
