"Chanel Allure Homme Édition Blanche is a limited edition fragrance and is available in 50 and 100 ml Eau de Toilette Concentrée sprays."
It looks like the Concentree the one and only Edition Blanche. It is excellent stuff. The bigger concern for me is that it says it is a limited edition. I have a large decant, but if this is true I guess I need to go ahead and spring for the full bottle.
