sosogu_ is an item that allows you to change the shape of a kettle's spout. By attaching it to the spout of your kettle, you can pour hot water in a thin, line-like stream, similar to a drip pod. The original sosogu_ engraving is carved on the side, with an underscore representing "pouring water like a thin line." The above is quoted from the product description on the WPB (a general goods store that handles this product) HP. Regular: Plug diameter 15-18mm ⚠️ Compatible with Trangia kettles 0.6, 0.9, and 1.4L Purchased at an outdoor shop several years ago. Used 4-5 times at campsites, but has been stored at home since then. There is soot and discoloration on the silicone part, possibly due to use with a kettle that boiled water over a campfire. I have confirmed that it works without any problems. Cancellations, returns, and refunds are not possible after purchase. Please confirm your order carefully, and be sure to ask any questions you may have. There may be oversights, so please refrain from purchasing if you are overly concerned about the condition or if you are concerned about used items. I live in a pet-free and non-smoking environment. Packaging will be done using recycled materials. By purchasing, I understand that you have agreed to the above terms. Thank you.
