Durable product
Great mat for desk or table for girls that love doing their own nails, or just to use to keep an area clean for a project. Can be rolled up and easily transported. Can switch sides as well! Great product and easy to clean.

Actual glitter instead of highlighter
Color: Gold, Size: 3.38 Fl Oz (Pack of 1)
I was looking for a glow body oil that had actual pieces of glitter in it, instead of just a body highlighter (like many of the other market glow oils) and this is exactly what I was looking for. It smells delicious and is very moisturizing. It does feel like an oil, but it is lightweight. I have the sol de janiero glow oil and the main differences are the pieces of glitter vs the highlighting effect. Its not an over powering amount of glitter but just enough that if the light hits you, you can tell there is a shine
