Good alternative to paving - color selection would be nice

I was recommended to the pharmacy this association. My son (6) often has the typical abrasions on his knees by several falls, but since he has quite a lot of hair on the legs, patches are quite a torture for him. This association is a good alternative in case of injuries, but the times have then a cover needed: a compress on the injury, dressing drum and away you go. Without discussion I can always pick up the Association again where we already happy times spent 30min when paving in the bathroom. And the colorful colors are good at child - has this been going so far, that he desperately wants to have a bandage, because it's kind of cool;) The price is great, much cheaper than the pharmacy. A star deduction that I can choose any color - Purple is not as good at a boy ...
