I purchased this several years ago and have used it with care, maintaining it well. You can adjust the gap in the wooden part with the screw on top. It feels very good, with a satisfying "shori shori" sound, as you remove the seeds from the cotton. For those looking for one! ※Instant purchase welcome. ※Can be changed to Yu-Yu Mercari delivery. Please let me know if you would like this option. ☺︎
