These are perfectly 3D printed building blocks. They are 1:12, 1:24, and 1:48 scales and are so easy to paint with alcohol paints!

You choose what scale you want. Now the half and quarter inch do work well in 1:12 because they can be considered nano block sizes. The 1:48 can have 1:24 ones that could be Duplo sized blocks. It's up to you! Mix and Match!
