One singular stem from the bottom, extends into two stems, and from two, it further extends into four stems

and this division continues as each stem extends and divides, creating this intriguing form that looks like a tree.

However, this characteristic is typical not for a tree but a marine plant in the ocean.

When we imagine a tree-like shape in our mind, we always imagine such a characteristic. To us, this dividing property is somehow rather symbolic.

We came upon the word, arbor, when we were looking for a word to describe this characteristic, rather than the tree itself.

It’s actually a word used to refer to a tree before it was being called a ‘tree’!

So we thought it was a perfect way to describe the shape we associate with trees, thus the name, ‘arbor’.

This item would be like a tree ‘larva’ which seems to have an adorable presence that seems so unique.

We hope you will enjoy the item which will look great not just on the ladies but the men as well!

Arbor is an original design by monocircus. 3D printed in Nylon plastic and hand-dyed in the various colors.
