Aberfanturning make all the pen boxes using local hardwoods such as Oak,  Ash, Beech  etc. 
 Mahogany and other hardwoods are used but any good quality hardwood can be used. 

Small barrel hinges are used so no screws are visible. 
Two magnets are in the wood so the box closes with a satisfying click.
The top of the box is a large flat surface and engraves very well.
Here are a few examples.
