How cute are those?! Tiny little glass bottles with corks. They don't stand up well, but think of all the mad scientist scenes you could create... Or turn them upside-down and make little Christmas bulbs or tiny snow globes??
Set of 4.
In the photo below, the line-up shows tiny bottles (left to right): one of the 12 Tiny Glass Bottles set, a Mini Inkwell Bottle, a Tiny Round Bottle (upside-down) and an Amber Even Tinier Bottle.
