It is long and slender and bends, so it fits in various places! I found a cleaning goods called "cleaning stick" at the 100-yen shop CAN DO.
A product with a cleaning cover attached to an elongated steel stick. Taking advantage of its length of about 46 cm and its ability to bend freely, you can clean hard-to-reach shelves, furniture gaps, sash grooves, etc. The dirty cover can be removed and washed. It seems that the replacement is also sold separately.
What I liked when I actually used it was that it could clean not only narrow spaces but also wide surfaces. If you fold it a little longer, you can wipe the top of the desk or the door of the cupboard at once. It was easy because I didn't have to bend down like wiping with a cloth.
A "cleaning stick" that has almost no thickness and is not difficult to store. Why don't you put it on standby in a place that you can easily reach and use it for daily cleaning? The price is, of course, 108 yen (tax included).
