The stickers for plastic beakers, etc, are fabulous. The iron-on ones aren't so good. I ironed them directly onto the care-label, as suggested, being careful to use the useful little bit of plasticky-paper (sorry, words fail me... silicone, is it?). Anyhoo, the ones I ironed onto the care labels have all come off in the wash, or peel off when the item is worn! I have since been ironing them onto the garment it self, much better. However, I have wasted a whole bunch of labels <weeps> I also recommended them to my boss who had similar feedback. Now I know it's better to iron onto the garment, I'm happier and will order more as my child grows. Thank you. ps: delivery to mainland Europe, where I am, was very quick.
