I use these too! Such a life saver, especially when you have washed something new and it has lost a lot of dye.SARD COLOUR CATCHERS. I have to sing the praises of this product as it has been a game changer for me. I got to test this product many many years ago and loved it immediately. I always separated my whites from darks and colours so this product lets me do a full load instead of smaller loads. The directions say use 1 sheet but depending on ratio of whites to darks I sometimes put in 2 or maybe 3 sheets but I use them again as they aren't completely used. In photo is 1 new sheet and I used 2 sheets in the wash that had 3/4 dark clothes.
They are available at Coles, Woolworths and IGA but not at Aldi
