other than epsom i think , hermes leathers are not embosed ! and the beauty of the grain is given by nature that is why they have veins and a show change during time as it is a living material it changes it is given its color by natural tanning and dyes made of natural extarcts that is to say no synthetics. the differance essentially is the look
togo is a bit more rigid but with time can become loose it is a small grain and may show veins it is very chic and never extremly thik though this may vary
clemence is a bigger grain soft a bit more shineer and definatly thiker often looks like a softer more plush leather shows less veins
fjord is a bigger grain with more of a matt look , divine on 40cm or bigger bags well on any bag it also shows veins
they all age in different ways but are all beautifull and even though the share a common look as in grainy leather, they are all very very diferent and beautifull in their own ways
