These adorable little glass bottles are just the thing for Fairy Dust Necklaces, Potion Necklaces (like in Harry Potter), or whatever else your imagination can come up with. Each little bottle comes with its own cork stopper. The measurements are approximately 21mm diameter, 40mm tall, and each bottle holds approximately 7ml (I've shown the bottle and the cork next to a quarter to give you an idea). These sweet little bottles are sold per box of 12.
