Because the price is cheap, I thought about it, but it's enough. I can use it firmly. As mop reduces the hair slender thinly, the replacement frequency will also increase. Because it is a consumable item, it is saved that the price is cheap.
Things that I have used until now are rusty with thick threads, but this item is narrow in width with eye thread, so draining with a mop squeezing device is good. Cleaning in a narrow place, it will not be clean with a big mop. I think that I will continue to buy it because the price is also cheap.
