The BLF 337 Crease Blending Brush (Medium) is a makeup brush designed for blending eyeshadow in the crease of the eye. This brush has a medium-sized, tapered shape that allows for precise and controlled blending in the crease area.

To use the BLF 337 brush, dip the brush into your eyeshadow and then gently blend the product into the crease of the eye, using back and forth motions. The tapered shape of the brush allows for a more diffused and blended look, creating a seamless transition between eyeshadow colors.

This brush is also great for applying eyeshadow to the outer corner of the eye and for creating a defined eye contour.

The bristles of the BLF 337 brush are made of synthetic material, which makes it easier to clean and prevents bacteria buildup. The bristles are also soft and densely packed, which allows for a more natural-looking blend.

Like with any makeup brush, it's important to clean the BLF 337 brush regularly to prevent bacteria buildup and ensure that it performs optimally. You can clean the brush by washing it with mild soap and water or using a specialized brush cleanser. Allow the brush to air dry completely before using it again/
