Such tiny little stools! This is for a set of 2, as shown (they arrive flat but can be put together in about 30 seconds... perhaps a bit more time for the glue to dry). The short one is 3/4" tall and the taller one is 1-1/4" tall.
See photo below for a size comparison with the larger Set of Stools - 1 Inch Scale (the shorter stool from each set is shown).
Set of 2.
This set is in 1/2" scale (1:24).
