hello @emma55,
it is interesting this form to know if it is an original article or a copy, another form to know if a tlf is original, is the weight because generally the imitations are always lighter than the original, it is common to find the tlf that are copies in informal sales where they offer you the opportunity to buy it fast to low cost, in 90% of the cases always it is a swindle for that reason we must buy where they give us guarantees on the product.
