^ That's the best type of packaging, nice and simple!
You ended up with the Vulfix 660S? Nice! Best £ for £ brush by miles! It's dead easy to get a good lather with Proraso, just follow everyone's advice above. Actually, I'll use it tonight and take some pics!
Here we go... a nice simple method for quick and easy lather.
1. Run brush under a tap (hot or cold) and flick off the excess water, one flick will do.
2. Swirl the brush in the Proraso pot for 10 seconds, not too hard and chuck in a few paint stokes for good measure. Make sure all the tips are loaded, if it gets too dry add a few drops of water. It'll look something like this.
3. Start swirling the brush on your face, in a bowl or on your palm (as I did here) the 660S is great for all methods. Only lightly press the brush down when mixing, maybe around about 5mm or until the top has flattened down halfway to the edges.
You'll get light 'proto' lather real quick.
4. Keep swirling and occasionally scrape the lather back in your palm/bowl/face from the brush. That's the stuff you need to 'work' into a full lather.
5. Add a few drops of water or quickly dip the tips under a tap/bowl when it gets a bit thick. I only needed to do this once or twice for this lather.
(Soaking the brush negates adding extra water but it's harder to get the perfect mix, adding it bit by bit makes it easier to see everything coming together and if you add too much water you can just go back to the Proraso for a 1-2 second load.)
6. When you can fill the brush with gobs of lovely menthol goodness start painting it on your face and enjoy
More than enough for 3 passes and touch ups.
Thick and glossy is great advice and don't be afraid experiment with consistency, even between passes, you can always go back to the tub/add more water, it doesn't take long.
Edit: Forgot to add the classic bloom shot
Enjoy the brush!
Can you still buy these at supermarkets? It makes the perfect blade bank, then safely recycle when its full.
