For larger bonsai are obviously scales. Bonsai are preferably shells that fit the tree. Not too big, not too small and a proper form.
The scale support Bonsai in the composition should and should not divert attention from the tree.
Quality Scales are hereby preferred. Quality Scales are usually hand-made scales. Potters who offer good handmade bowls are less and less. Both in Europe and in Japan there is therefore an increasing demand for this type scales.
