Grafting Tools

[Mochi01]

Hello, i want to have 50shades (rare) look in my uniques sweet candy stripper costume. So I can have 50 shades look with sweet candy stripper stats. 

What grafting tools should i use ? Unique or Rare ? 

And do anyone know how much uniques grafting tools and rare grafting tools if i sell it in auction house ? 

Thank you

Rare Costume + Unique Costume = 1 Unique Grafting Tool

Rare Item + Rare Item = 1 Rare Grafting Tool

Always need 1 to craft 1 Item.
