I don't like to waste, so I'm offering these "blemished" versions at a discounted price. These may have the following issues, but not limited to: large visual blemishes on the exterior surface like major scratches, dents, chips, or anodization issues. Despite these visual blemishes, they are fully functional. Future configurations being developed: 58.5mm 49mm 54mm 58-42mm 58-30mm 54-42mm Does not include basket, portafilter, dosing ring, stand, or other tools pictured.
