Phellem is the outermost layer of the tree bark, and this collection treatise on its incredibly fascinating biodiversity unveiling any range of colors and the most unimaginable textures.

When bark is damaged a natural defense mechanism intervenes, a complex liquid substance hardens in contact with air creating a sort of conservative barrier keeping the vital wood layers away from bacteria, fungi and parasites. It’s the resin.

In a similar way, alcarol preserves the bark of different species covering them with an innovative bio-sourced transparent resin, functional declination of the tree’s natural process.
