USA-made. 3D-printed PETG. Air-pruning mesh bottom. Bonsai Shoes training pots are designed and printed in the United States from premium PETG — strong, UV-resistant, and unfazed by water, chemicals, and cold [only about 10–15% more brittle in freezing weather]. The thick walls insulate roots from heat and cold snaps.

The Modern Oval

A sleek oval with clean, simple modern lines — the all-rounder of the Modern series. Suits just about any tree that belongs in an oval: pines, junipers, maples, elms.

Air-pruning mesh bottom

The bottom is a raised air-pruning mesh: water and oxygen flow freely, and root tips that reach it stop and branch back into a dense, fibrous root ball instead of circling the pot. A single air/drainage port in the lower perimeter wall adds extra exchange, while the solid walls keep the soil from drying out too fast.

Three ways to use it

• On a solid surface — roots grow through the mesh and colonize below for maximum vigor. Trim them back at least once a year so they don't thicken and clog the mesh.
• On a mesh or grated bench — root tips hit air and prune themselves, back-budding into fine roots. The classic air-pruning setup for a nebari-ready root system.
• On soil or the ground — roots escape into the earth below for the strongest growth while the pot holds a compact root ball. Trim yearly to keep the mesh clear.

Sizing

Shoe size = the pot's largest exterior dimension in inches [usually the width across the top]: a size 10 is 10" wide, a size 8 is 8" wide, and so on. As a rule of thumb, pick a pot about two-thirds the height of your tree for upright styles, or match the pot's width to the tree's canopy spread.
