The expiration refers to the time till the expiration date on the manufactured item. This does not refer to the amount of time that the item is intended to work for.
For example:
1-2 MONTHS means that an item will have an expiration date between 1-2 months from the purchase date. If you purchase an item in July, the expiration date on the box will be either August or September.
EXPIRED means that the item is past the expiration date on the box, but the item can still be used effectively. For any items that don't work as intended, we will replace it at no cost to you.
