Monika Blunder Blunder Cover All-in-One Concealer/Foundation. In the shade 2.5 Zwei which is for fair, soft warm pink undertones. Blunder Cover is an all-in-one foundation/concealer that can be sheered out and used as a natural, comfortable base, or built up as a concealer in areas that need more coverage, with an always natural skin-like finish. The multitasking formula can also be used in lighter/darker shades to highlight and contour. Used only twice with a clean sponge and sanitized. Wrong color for me.
