There are two definitions of heatstamp.
1. Relates to authenticity. So if someone asks for a picture of the heatstamp they are referring to the areas of the bag where there is the indented stamp that says "Louis Vuitton Made in ______"
2. Heatstamping can also be done on bags for a personalization. Boutiques can heatstamp your initials, etc. in various colors. This can be done for free.
Hope that helps! And welcome to tPF
p.s.
can you heatstamp miroir?
i want my initials on the zipper pull of the pochette!
I don't think you'll be able to heat stamp Miroir... it might melt?
And thanks Mshel!
