Will leak; very delicate; very limited - Matador FlatPak Toiletry Bottle

What does "anything from soap to toothpaste" mean? It means most soaps and toothpastes, and that's about it. The FlatPak loses its seals/welds with even trace amounts of nearly any kind of alcohol, so it will certainly fail with hand sanitizer, but will also fail after longer periods with more mundane items like sunscreen or ointments. Honestly, I regret ever purchasing these. I've had several leak on me that contained sunscreen and shampoo. This made a huge mess and ruined several nearby items in my pack. Just using a product's original packaging seems like the best bet.
