Courtland Steady Sink or 3M Uniform Sink 【ST-13S/type IV】 This item has been stored for a long time. ● I'm not sure which one it was, but I don't think there was an ST13 for the Uniform Sink at the time. I've forgotten. ● I actually measured it for the listing. It was about 10.2m/28g. I used a household food scale, so please allow for some error. ● It was only used once for casting practice in a lake, so I don't think there are any noticeable scratches, but please judge the condition from the images. Please forgive any other oversights. ● Both ends of the line are cut, so please process them yourself. ● Please refrain from purchasing if you are concerned about even the smallest details. ● Thank you for your understanding.
