10-speed are polish drops that make the drying process faster. You apply 2 drops per nail and let it spread on its own. The producer claims that this dries polish to touch in 1 minute and to go in 5-7 minutes, and I must say these promises are not exaggerated. My nails are completely dry within not more than 10 mins, helping me avoid many nasty surprises. The drops are very easy to use and efficient.
