myco- it comes in the typical 6oz packaging (think fantasia serum, same size and all) Its nice and thick and does wonders for detangling and adding that extra shine boost. Costs like $7, and i prefer it over both the Vive serum and Arican Royale's diamond drops. I think it does more in terms of controlling frizz and so forth. It smells kinda perfumey, but i dont mind it too much.
Its actually the serum of choice in many salons around here.
