Lec Geki-Ochi Kun High-Density Brush Treloop (for stairs) is a reusable dust remover. I am selling this because I accidentally bought too many. I have one more, so if you would like to purchase two, please leave a comment and I will accommodate you. The purchase date was December 2025. This is a convenient cleaning tool that cleans the mop just by passing it through the case, and it can be used repeatedly. It is also easy to store, and can be compactly stored when not in use. It is lightweight and easy to hold, making cleaning easy. Please understand that this item is stored at home. Thank you.
