1. Pueen or MoYou plates come highly recommended. Try to avoid "
gimmicky" designs as you may not get as much use out of them as some more
classic ones - like, say, roses or stripes. Case in point, I have two
goth plates I barely touch. Pick stamping plates appropriate for your preferred nail length.
2. ACETONE. A BIG OLE BOTTLE OF ACETONE. This is great for cleanup around the edges of your nails, but you also definitely need it for cleaning the plates. Normal nail polish remover may leave a residue.
3. White paper and black paper to practice on. The black paper is great if you have pale stamping polishes, and for testing potential opacity on top of dark nail polishes.
4. Sticky tape! This is great for lifting off the residue around your nail, and it's a shitload gentler than regularly using acetone.
5. Cuticle oil.
6.
Black stamping polish. Great to start off with. Any nail polish that is totally opaque in one coat can be used for stamping, though, which is why all of my metallic stamping polishes are just bog standard ones.
7. Nail brushes. You might have to fill in some voids, and they're great for cleanup when dipped in NPR or acetone.
8. A squishy stamper, like the MoYou one I recommended above. These pick up designs really well.
9. A scraper. These usually come with any stamper so unless you get a shit one you shouldn't need to invest in one.
10. A quick drying top coat, like Seche Vite or the HK Girl topcoat.
