Kiko is a well known brand worldwide, especially in Europe, but they are slowly making their way into the United States and opening stores countrywide! One of their most famous products is the Water Eyeshadow in 208, dubbed the Whisper of Gilt/Heatwave dupe throughout the makeup community.
I’m sure you’ve heard of Swirl and Sparkle if you’ve been on Instagram recently. They are a smaller indie brand that sells solid brush cleaner through Etsy. The full size containers (1oz-4oz) have the option to add scrubbing diamonds to the inside of the cap, which I totally recommend adding. They currently sell their cleaner in four scents: Toasted Marshmallow, Coconut Mandarin, Chocolate Cake, and Samoa Cookie + an unscented version, and a goat milk base and a vegan shea butter base.
