I bought Epic (forest green), Center Stage (deep ocean blue) Luna (champagne) and Jester (yellow olive green). They add an amazing pop of colour to any eyeshadow combination. They're an affordable and less messy alternative to loose pigments. They come packaged in cardboard slots so you can easily add them into a customised palette.
The wear of the shadows tends to vary with some lasting slightly longer (Epic and Jester 6 hours) than the others (Luna and Center Stage 4 hours or less). All the shadows except Luna have a smooth consistency and glides easily across the lid. Luna tends to pile up and crumble when I swipe my brush in the pan. Note that this shade is from a makeup palette (MUG x Manny MUA collaboration) so I'm wondering if the formula is different.
My only issue with this product is the inconsistency in the lasting power. I have oily lids so this could contribute to the average wear. Even if I pack on the base in the hope the shadow will adhere to it, it doesn't seem to prolong the wear. They perform below average in hot weather possibly the heat warming the cream component of the shadow and breaking it down more easily. Despite this I would happily repurchase other foiled shadows from MUG because I can still make them work for me - they're easy to use, they have stunning pigmentation and are affordable.
I own 3 of these, and have had them for a few years now, they're absolutely gorgeous. They're duochrome and they show up so well on the eyes and they blend super well. I don't know if makeup geek still sell these as they've changed their eyeshadows to the matrix system. But these are still gorgeous many years later.
