I don't recall using these, but some may have been rinsed with water. Only items without stickers have their original boxes. These are items that have been stored for a long time, so please refrain from purchasing if you are sensitive to such things or if you are seeking a perfect item. The size is approximately 13.5cm x 10.5cm, and the height is approximately 5.5cm (excluding the knob, which is about 1cm). Please allow for some error. Please examine the photos and purchase only if you are satisfied. No returns accepted.
