Three ways of identifying  genuine leather :Watch,touch,smell

A Watch:Look at the lines, look at the pores, look at the base and cut, see the water absorption.

1,Look at the lines ,now the lines of genuine leather and artificial leather are almost the same .So this way did not work .

2,Look at the pores,the pores are so small .Shall I bring a magnifying glass when I buy bags ? 

3,See the water absorption,the surface could not absorb water and we could not see the inside situation .

What's more ,water would harm genuine leather .This way would not work ,either .

4,Look at the base and cut.Cut the bag and see the layers .
