Really depends on the kit. The ones I’ve used don’t have a dropper at all. They came with a prefilled (capped) tube. Certainly those aren’t going to be mistaken for eye dropper bottles. But not all kits are the same. (The ones I got are more likely to be accidentally spilled when prying those caps off. Maybe more of a hazard.)
