I'm a huge fan of de-potting and decanting products into compacts and palettes. It makes my life much easier when travelling with my kit and is just generally a much more organised and convenient way of storing products.
I had been lusting after this Japonesque palette for months & months and finally picked it up from Guru Makeup Emporium at the IMATS in January. So far, I've de-potted most of my MAC lippies. I still have cream colour bases & other non-MAC lipsticks to go. It's a fairly messy & laborious process and requires a good few hours of time, which is why I'm only half way through!
I don't do this for my own lipsticks - I'm too much of a packaging lover to do that, especially with lipsticks from Estee Lauder or YSL! I'd never do that to them!
