I use the liquid detergents Yvette Care and Yvette Black for delicates. These are only available in sachets, which is certainly good for the environment. However, I find it very impractical for dosing. In order to be able to decant the detergents, I first bought the corresponding products from the competition in a bottle (Perwoll). I would like Migros to offer an empty, neutral bottle for free or at a very low price so that you can decant the detergents that are only available in (refill) sachets.
