Here’s a little hack I discovered worked very well when I need to send sunscreen to school with my kids (for sport, outdoor activities and excursions). I have purchased little clip on bottles before but I find the lid gets bumped open and it goes everywhere. I’ve also tried roll on sunscreen. These are good too, however they are expensive and I find that the kids don’t end up putting enough sunscreen on this way. Instead, I saved a little makeup jar (think eye cream, moisturiser, concealer pots) and anytime I need to send sunscreen to school with my children, I just fill it up and the screw on lid is perfect! No spills! I do pop it in a ziplock bag, just in case. Works really well.
