NOTICE: All products categorized under "Glitter" contain Polyethylene Terephthalate, also known as plastic or PET glitter, and it is typically cosmetic grade glitter. Inclusion of this ingredient sometimes carries a warning (in the US) that the product is "not intended for use in the immediate eye area." This ingredient has not been approved for usage on the eyes per the FDA. In recent years, some brands are including this product in their eyeshadows without any warning or callout and effectively marketing them as eyeshadows or including a symbol of an "eye" which suggests eye usage. Via CosIng for EU, PET glitter is permitted without any restrictions or limitations. For an in-depth look at whether cosmetic grade glitter is safe, please view this post.
ColourPop Cloudy Pressed Powder Shadow ($4.50 for 0.04 oz.) had a lighter, white gold glitter base with flecks of larger pink and gold, hexagon-shaped glitter. It had a mix of glitter sizes (and it did include plastic glitter, which was listed as not safe for use on the eye area) from finer micro-glitter to larger, hexagon-shaped pieces.
The glitter seemed suspended in a transparent base, but it still had semi-opaque "coverage" from the amount of glitter in it. The product dispersed evenly with a brush or with fingertips with minimal fallout during application. During wear, it had some travel/migration but a lot of it stayed in place.
