What to know before buying
Listing details to confirm
Listing details are inconsistent: the listed dimensions include a mass of 90 g, the separate weight is 0.09 Kilograms, and the stated size is 91 g (Pack of 1). The product name and use copy call the treatment an oil, while the item-form field says cream. The title mentions free replacement pads, but the explicit included-components list gives ingredients rather than kit accessories. Confirm the selected listing's size and kit contents before purchase.
