My dearest friends Urban Decay has finally heard us crying for a normal tube. Ladies and gentlemen, I present you Urban Decay Eyeshadow Primer Potion Professional Size
No need to cut, depot and carefully store your primer from a weird tube. Though it costs $11 more it's almost 3 times bigger (0.85 OZ vs 0.34 oz).
This is definitely good news!
