I'm personally not someone who loves eyebrow products in general, so take this with a grain of salt if you find a review that talks about this product more positively.
This palette comes with an angled brush used to apply the eyebrow product, a spooly, a small pair of tweezers, a few eyebrow stencils, eyebrow gel, and two shades of eyebrow product, one light and one dark. The product also has instructions on how to use it. Talking first about these instructions, I find them to be ridiculous. They call for blending the light and dark shades together to match your hair shade, holding the stencil up to your eye and simply using the wider side of the angled brush to fill them in, followed by coating the spooly in the gel to glide over the finished brow to lock things in. But literally everything sucks and let me explain
By mixing the powders, application becomes patchy in that some places are lighter and some are darker, and its near impossible to find your own hair colour. The stencil is decent but it's obviously standardized and might not match some peoples' faces, even when you use the different archs. It's also too easy to shift the incredibly flimsy stencils and get product all over your eyes and forehead; they smudge so easily. The gel is a good idea, but the powder takes too long to set and a lot of people don't have the time to wait before setting with the gel, thus ultimately getting the powder everywhere.
This is a terrible product and for eyebrows, please save your money and buy powders/pencils/dipbrows etc. already made for your own hair colour.
