This helmet is in excellent condition. There is only 1 mark on it which i have tried to show in a photo. There is a red circle round it and an arrow pointing at it

I bought this helmet about 12 years ago for my partner. She was going to wear it on the back of my bike when i completed the renovation.

Bike has gone, so helmet no longer needed

The helmet has spent the entire time in its blue bag on the bottom shelf in the spare room. Which may be where it got scratched, the mark does some to be in the same place as a hole in the bag.

The visor and all the nose guards etc are all in place and are in good order. 
You could take it out of the box and use it straight away.

The bike is marked as a 57m

The year of manufacture is 1997.
