This product comes in a small tube with .35oz (10g). I paid $15 and had the choice between two shades: Bisque and Natural. I opted to buy both because I wasn't entirely sure of the match.
The product is easy and tidy to dispense, and not much would be wasted since it's a tube format. The consistency is similar to a liquid foundation. The bisque shade has yellow tones while the natural one is more pink. Both colors seem very dark, and there are no additional options for lighter skin tones.
The product glides on easily and dries quickly. My shadow adheres to it well and spreads and blends easily.
However, I will not repurchase this product because both shades are way too dark for my skin. For dark or highly pigmented shadows, I can see this working okay. However, when used with any light or sheer shadows, the primer product is totally visible and its poor match with my pale skin is very obvious.
If Studio Gear adds additional shades or transitions to a single, sheer product color, I will consider trying this again.
