Nailmatic Bath Bomb - Comet

What you're getting

Drop this into the bath and you've got yourself a fizzy blue affair that'll keep your kid entertained while actually doing something useful. It's made to be gentle on sensitive skin, with citric acid, camomile extract, vitamin E, sunflower oil and sweet almond oil doing the heavy lifting—moisturising and cleansing without any preservatives hanging about.

The whole thing's made from proper gentle ingredients, and the packaging is recyclable with vegetable inks printed on it, so you're not adding to the guilt pile.
