The difference of our Cashmere & Velvet & Mink:
Cashmere: super soft x super fluffy x dark matte black
Velvet: super dark matte black x very soft x very fluffy
Mink: jet black, little shinny. It looks the blackest of all.
We suggest you:
If you like soft and fluffy lashes best, then choose cashmere
If you like extremely black but matte, then choose velvet
If you like black black black, and more economically, then choose mink
