All of our 3D puzzles are made of 3mm Basswood/Birch wood and include assembly instructions.
Butterfly assembled size is approximately 8" wide X 14"deep X 11" tall
Each part is numbered making assembly easy (once assembled all numbers are hidden)
We have carefully sized all of our puzzles to be secure once assembled however due to wood being a natural product we do recommend having sand paper and glue available during assembly.
