Presently there are two versions of educational puzzles: Lower 48 U.S.A. and the Periodic Table.
The U.S.A. puzzles can be customized quite easily for individual children by adding home location, name, etc. The USA puzzle is made from two pieces of cherry laminate. The lower piece is engraved with state outlines and geographic features. The individual states are then added to the top layer. Some eastern states have been combined for structure sake.
The periodic table puzzle is a bit more complex than the U.S.A. puzzle. It is made from mirrored acrylic. It’s best use is to be something for a child to play with when young to become familiar with the structure and the terms. It can be backed and taped together and hung on the wall to use as a study guide.
