how long after manufacture can i use it. I've got 2 bags that i purchased from you last august 1 batch number 21/18. and 1 29/18. thanks
Dear Daniel,
Shelf life of the Nanofug Premium is 12 months, therefore as long as it's not been opened it can still be used within several months.
If the bags have been opened they are probably no longer usable and you will need to supply a new product.
I will be happy to assist if you have any questions.
Kind regards
