My poor vegetarian self has an issue with Marrow as a nail polish name. It's just not... appetizing. Especially knowing that this was exactly what Butter London was aiming for when creating the polish. In their own words:
Hand mixed for the Vena Cava designers, who named it after the dark purple, rusty center of a bone.Whatever. This is a pretty dark purple that looks almost creamy with the microest of all micro shimmer. It's a wonderful mid-winter color, and I especially like that it doesn't look black even in the shade (unless it's really pitch dark).
While the color of Butter London Marrow is almost opaque even with one coat, application goes somewhat streaky so a second and even a third coat are recommended. I've experienced chipping at the tips around the third day, but I'm really hard on my nails. Reinforcing the top coat every day always helps with preserving the polish (and my sanity. I can't stand chipped nails).
Butter London Marrow Nail Polish ($14) is available from Ulta, Nordstrom and butterlondon.com.
