Barry M are a UK drugstore brand which sell many great products including a wide range of Dazzle Dusts and Fine Glitter Dusts. These loose products are highly pigmented and most are packed full of shimmer and sparkle, though there are a few matte shades as well.
Each little jar contains a large amount of product, I would estimate around 2 grams (I've been unable to find the actual weight on either the product or online which is a downside). It is stated on the bottom sticker of a jar if it is not safe for use on eyes or lips. These retail at £4.59 each so are very affordable. There are often promotional offers in Boots and Superdrug to the likes of 2 for £8 or 3 for £10 as well as freebie products if you spend over a certain amount.
