This is not a 2L product. This is a sample size for those who want to try it. Purchased in late August of this year. It will be shipped in a new container that is "easy to store and use as is" immediately before packaging. Can be used for all pets' feces and urine. The undiluted solution will be sent, so dilute it with tap water to about 10 times the volume and let it sit for about an hour before use. Once diluted, it is recommended to use it within 1-2 weeks, so it's best not to dilute it all at once. Please refer to the instructions in the images for detailed usage. I apologize, but the instructions are not included. The undiluted solution has a slight odor, but it disappears in about half a day. ・ 70ml 650 yen ・ 120ml 800 yen ・ 210ml 1090 yen is also available. ・ 350ml 1570 yen ・ 420ml 1790 yen ・ 500ml 2020 yen ・ 560ml 2230 yen ・ 630ml 2450 yen are also available, so please comment if you'd like one m(_ _)m
