A quality, glitzy little bottle of shine
Color: #07 Golden, Size: 0.17 Ounce (Pack of 1)
Lovely spray shimmer POWDER, really great for just spritzing on. The little bottle is adorable, easy to carry in your bag (has a little safety lid) and great for a little gift. It gives little puffs of glittery powder and it stays nicely, though I almost never perspire.

Wonderful product but only half full
Color: #02 Champagne Gold, Size: 0.17 Ounce (Pack of 1), Color: #02 Champagne Gold, Size: 0.17 Ounce (Pack of 1)
I love this product but I'm incredibly disappointed the bottle is only half full. It is not sticky and has a beautiful spray distribution. It is easy to apply but also appears the glow fades easily. This product is incredibly functional and beautiful. 5 stars if it was a full product
