This is a set of 4. I purchased a large quantity for business use, and I am selling them to clear out my inventory. This product retails for over 4,000 yen for commercial use. I have a considerable number of these, so I am offering them at a great price. I also use this product at home. It's convenient for various areas like the kitchen, bathroom, entryway, etc., and it's a spray type. Available from 2 bottles. Purchasing multiple sets is a better deal. I've attached a URL as a usage reference. There's also a video, so please take a look if you'd like. (※Reference URL) Basically, I can ship the same day. ⸻ 【Set Price】 2-bottle set: 1,280 yen (640 yen per bottle) 4-bottle set: 2,280 yen (620 yen per bottle) 6-bottle set: 3,480 yen (580 yen per bottle) 8-bottle set: 4,480 yen (560 yen per bottle) 10-bottle set: 5,480 yen (548 yen per bottle) The more you buy, the better the deal. ⸻ Reference URL: https://qvc.jp/product.718140.html
