A pop and cute triangular pyramid painted in four different colors
I think it's probably a math textbook or something.
It is unclear what is to be learned
I don't know if it's actually a textbook.
Made of plastic and has a light texture
Put them in a transparent container or just line them up.
It looks like you can enjoy various ways of placing it.
As an aside, when I saw this, I thought of the four color theorem.
When coloring a flat map so that adjacent colors do not overlap
All you need are four colors
It might be fun to prove it with this triangular pyramid.
Sold individually
The size is the length of one side of a triangular pyramid.
