Manufacturer: Saraya Product Name: [New] Hand Sanitizing Alcohol Gel (1L) x 10 bottles Quantity: 1L x 10 bottles <Supplement> This product dispenses a generous amount of gel with each pump, so about 1/5 of a push is the appropriate amount. (If you dispense too much gel, a slippery feeling will remain for a while.) When using, please adjust the amount you press by wrapping a rubber band around the nozzle tube to prevent over-pumping. <Condition> There is no expiration date on the product, but it is from the early days of the COVID-19 pandemic, so I believe it has been about 5 years since it was manufactured. It is unopened, so there should be no problem with use, but please refrain from purchasing if you are concerned. By the way, I am currently using the same product myself, and I have not experienced any particular problems.
