Quality Declaration:

Product units classified as A Quality should not contain external scratches or visible marks that can be seen when assembled. Internal defects and marks not visible when assembled (including hook marks) are not considered B Quality units.

Screw holes are not fully anodized or coated and there may be small marks near the hole opening.

We try to use real photographs as much as possible to represent the keyboard product as well as possible, but we occasionally use renders to complete these photographs.

The presented render images may differ slightly compared to the final product.

Colors in the final product may vary due to renders being made under idealized artificial lighting.

Raw or thinly plated brass naturally oxidizes and forms patina. Small stains and color changes may be visible.
