Beware of packaging and bleach on clothes *by E***1 on 20 December 2018* Does it's job. Packaging could be better. On opening there was some powder residue which flew around and before I knew it had got on my favourite black top which now has bleach marks. Despite trying to dye my top to hide marks and even trying to buy another one the same I have been unlucky. SO BE AWARE WHAT YOU WEAR WHEN OPENING THE PACKAGE!! Especially the first time BEFORE you get to the earning INSIDE about bleach.
