EBay Bidder in China - Help Needed!?

afterglow_2

I am selling a SLR film camera on ebay, only for about £30 have received a question from a bidder in China, asking if i can post it there.
they have paypal so would be paid, and they have good feedback score, but are there any issues about posting to mainland China, with customs, safe delivery etc??
any help would be greatly appreciated , ta!

looked on royal mails site, and might need a customs declaration slip, looked on HMRC site and doesnt specifically say anything about China, but the fact that its a film camera may affect the declaration??
any advice??
