For many dioramists, the roots are the most critical part of a tree model. They anchor the scene to the ground. Tree 4 features an aggressive, exposed root system. These roots snake over the base plate, creating natural crevices perfect for applying static grass, fallen leaves, or small debris. The interplay between the organic wood and the earth is seamless, blurring the line between the object and its environment.

In the Tenkei Kobo catalog, is a specific individual tree within the CS15 collection. While the technical "story" is about its utility as a design tool, its presence in a project usually serves a specific aesthetic purpose:

The CS15 is the "medium" platform in the Cutoff lineup, smaller than the hulking CS20 but larger than the delicate CS10. However, the specific variant is where the legend truly begins.

Mount on a black lacquered wooden base with a small brass plate engraved “CS15 – Tree 4 – Tenkei Kobo.”

The is perhaps the purest expression of this philosophy. By isolating a specific section of a structure or nature—essentially "cutting it off" from the whole—the studio forces the viewer to focus on the texture, the weathering, and the form. It removes the distraction of context and leaves only the essence of the object.

Tenkei Kobo does not take orders. They release batches when the mood strikes or when they find "sufficiently imperfect" brass stock. The is the rarest subset of the CS15.

The -Tree 4- is exclusively offered in "Burnt Indigo." The brass dial is flame-treated before the final machining, giving the crevices a deep blue-black hue while the raised "branches" remain a ghostly silver.
