Vavona burl comes from the root of the coastal redwood (Sequoia sempervirens), which grows in the coastal areas of northern California and southern Oregon. The redwoods can grow up to 300 feet tall with a trunk diameter of 20 to 25 feet. The tallest living specimen is about 328 feet tall and is in Redwood National Park in northwestern California. It is the tallest tree in the world. Redwoods are also some of the oldest trees in the world, with 600 years not an uncommon age. The oldest recorded age was 2,200 years based on the rings. The root burls can assume gigantic proportions. Digging them out is quite labor intensive which makes this burl very expensive.
This Pen Blanks has been stabilized with Plexiglas® (PMMA) and fully penetrated. It will no longer absorb water, is dimensionally stable, and will no longer crack. It can be easily worked, but it does not react well to excessive heat during processing, so take care when sawing, drilling and grinding. (When it gets very hot, the PMMA begins to smear.) Very easily worked with sharp tools, but the odor stays within limits and is negligible. The stabilizing gives this block excellent hardness, durability, and stability. It is therefore suitable for heavy duty applications or in areas that get wet, such as outdoors.

Finely grained wood may contain imperfections such as open knots, bark inclusions, or cracks that are typical of the species. These flaws come from the way the tree has grown and are completely natural. They can usually be filled with low-viscosity cyanoacrylate (super glue) and wood dust.
