The Stamm Boom

• Only local, regional, and selected woods are used (e.g., pine, birch, larch, oak, ash, plum, maple, or cherry). The wood comes, among other things, from tree care companies that would otherwise shred and burn the wood.
• Staining and oiling with linseed oil or 2-component varnishing possible for an additional charge.
