[Closed] Leaky forks advice

I have just sold a set of Rock Shox Recon air solo forks on the 'bay, but when i was packing them up after the auction had finished i noticed a few drops of oil around the lockout dial. Is this amount of oil anything to worry about, does it suggest a service is needed or are they ok? If i was using them myself i wouldn't worry, but as i've potentially sold them i am a bit concerned they will be knackered after a few rides.

Obviously, i've let the buyer know of the issue and offered a refund if they aren't happy- waiting for a response.

Any advice appreciated!
