A listed price is the price of the catalog unit shown on that product page, in Indian rupees. Pack sizes named on the page are the packs the plant can fill. They are not separate prices unless a price is printed next to that pack.
Title in the goods passes when the order is paid, or when a cash-on-delivery order is handed over. Risk passes when the carrier delivers.
The grades are industrial and automotive lubricants. Use the viscosity and specification printed on the page and on the pack. Luvox does not publish a specification that is not on the product page.
