SHAFIRE Double Ended Makeup Brush Pen Blending Powder Foundation Eyeshadow  (Pack of 1)

A double-sided eyeshadow brush typically features two different brush heads on opposite ends of the handle, designed for different purposes or techniques when applying eyeshadow. Here are a few common variations of double-sided eyeshadow brushes: Shader brush and blending brush: One end of the brush has a flat or slightly tapered shader brush, ideal for packing and applying eyeshadow onto the eyelid. The other end features a fluffy blending brush, used for seamlessly blending and diffusing eyeshadow in the crease or for softening harsh lines. Flat shader brush and smudge brush: One end of the brush has a flat or paddle-shaped shader brush for applying eyeshadow to the lid with precision. The other end features a smudge brush with shorter, dense bristles, used for smudging and blending eyeshadow or eyeliner along the lash line for a smoky effect. Angled brush and crease brush: One end of the brush has an angled brush head, which can be used for precise application of eyeshadow or eyeliner along the lash line or for filling in brows. The other end features a small, tapered crease brush for blending and defining eyeshadow in the crease area. Sponge applicator and fluffy brush: One end of the brush has a sponge-tip applicator, which can be used for packing on or intensifying eyeshadow color. The other end features a fluffy brush head, often used for blending and diffusing eyeshadow or applying a transition shade. These are just a few examples of the combinations you might find in a double-sided eyeshadow brush. The specific brush heads and designs can vary between brands and sets, so it's always a good idea to check the product description or packaging to see the exact brush heads included in a particular double-sided eyeshadow brush.
