I got from sources pjgh recommended (Earlier on in the thread)and they are superb.
Amazing value.
Last days.
I have yet to see the volume decrease

Scent is incredible.
Again, this is something else I am a complete noob at.
But I love the oils.
The ones I have that seem decadent are (some more than others)
Black musk
Egyptian musk
Mukhallat maliki
Darbar
Don't get me wrong, they smell absolutely gorgeous and amazing.
Perhaps I need to get used to smelling like that.
(I am a simple kind of bloke.)
I also got some from pjgh as a pif to play with
khus fresh grass
lily flower
khus dry grass
plus i have
orange blossom
lime
cinnamon
mysore
honeysuckle
The latter I have played with throwing in amongst the others
In general, this way of doing things is way more fun than buying a spray that someone else has decided suits you.
