Eye cup shows some wear, but it looks good. I don't know what camera brand it might fit. 

ID is 21X18mm. 

Eye cup will be mailed just as pictured, so please look at the pictures above.  I will pack it well to protect it from damage during transportation.

Shipping is free within USA and $7 via first class USPS air mail service worldwide . You can choose faster (and more expensive ) shipping if desired during checkout.
