Approx. 17mm x 11mm. I like the light weight and thinness for layering with other bottles in a shadowbox without much depth.
These bottles are also included in the Magic Potions Kit; see all the other kit components available to buy separately.
See the small photos below for a size comparison with some of the other resin bottles also in the Magic Potions Kit.
This item is in Dollhouse 1:12 Scale.
