Colours used:
Base - Sally Hansen Golden-I
Stamping polish - Essence Galactic Black
Stamp - BM210
Don't think this picture shows it sufficiently but Golden-I was more shimmery. 2 medium coats shown above. You can have another look at Golden-I in this post where it was sponged on. Galactic Black was actually fainter in real life so I decided to invest in a black Konad polish after that :p
Update: I have better plain swatch pics of Sally Hansen Golden-I here.
Have gotten 2 sets of plates from Bundle Monster so you will be seeing quite a number of stamped manis in the future!
