Shipping method cannot be specified, generally no price reduction. Some discoloration present (see images). Please inquire if the condition is unclear from the images. Please purchase only after you are satisfied. I've been storing this for a long time, and it appears there's some discoloration on the K18 portion. The ratio of K18 to PT900 is approximately 7:3, with K18 being the larger portion. The clip (receiver) silicone parts will be included. Wiped with alcohol. The spring strength is strong, so it won't fall off easily.
