I have removed the plastic and used it only once. This is a set sale with professional products used in beauty salons. It's a great deal, with a total of 11 uses for both items. - Capacity: 100ml - Product Name: M Plus Serum Oil (Hair Oil) - Purpose: Hair Care - Design: Pump bottle Despite being an oil, it doesn't feel sticky and blends into the hair as if absorbed, providing thorough moisture. When used on towel-dried hair after a bath, it creates shiny, smooth, and glossy hair just by drying. Recommended for those who dislike heavy oils, those with hair damaged by hair color, and those with unruly hair. Contents: 100ml Please note that this item is stored at home and is non-returnable/non-refundable (NCNR).
