How can I get in contact with a buyer that bought something 65 days ago?

[ricky_the_rockstar]

Hello, i sold something 65 days ago and the item is no longer listing in my "sold" section, but i can still reach the listing looking at completed items, i can see the buyer's ebay member name but i cannot figure out how to contact them. i tried google and the advanced search method and that just gave me the buyer's real name, loaction and phone number, but i would just like to send them a message via ebay, is there a way to do that?

i'm wanting to contact them because i just discovered i forgot to includes some items with their purchase and i feel bad about it
