Topshop Nails - Green Room VS Butter London Slapper

I ordered this from nordstrom for $10. Glad to see availability in America and with free shipping! The formula is somewhat on the sheer side, however it's beauty makes it worth the extra coat(s) needed. I was worried this would be the same color as Butter London Slapper that I already owned, however it is definitely more green and brighter! I do prefer the Butter London Formula, but in person the colors are not as similar as I feared.
