Hi sublime_trash, i have some fantastic whitening strips – theyre very gunky & take 20mins to work, but then you can double up & do it twice inone day if you have a special event to go to. Unfortunately i cant find the box since i moved a few mths ago, & i cant remember the brand, i think it was colgate or something very well known. but i got them in Canada 2yrs ago – so there might be something in what Miss W said about Aussie one not allowed to have enough bleach… but these work great. They may have an aussie version, or you might be able to order online? As soon as i find them, i`l let you know the brand.
