The most common items for women are all kinds of cosmetics, and it is often difficult to remember their shelf life. If you put a small label on it, you can see at a glance whether it is a toner or a lotion. The outer packaging of cosmetics is thrown away, and the shelf life is often forgotten during the use process. Using the D30 portable thermal label printer to print date labels to mark the expiration date of the item can avoid the embarrassment of continuing to use it after the expiration date.
