thank you Celestino on the Dark Vetiver. I cannot remember where, but I read that WK will transition some of their scents to Donkey Milk.
Noticed Cuero Oscuro special edition Donkey milk is now available from Top of the Chain here in Canada.
They do periodically have a limited edition runs of an existing scent made in the donkey milk formula. Check the "up next" on their website for the special edition release dates.
