• The STEM was developed by the fine folks at ONA Coffee with the intent to create a tool to increase workflow, improve cleanliness, and protect your scales.

    The STEM acts as a platform between the espresso machine and the scale, protecting the scale from water damage and allowing baristas to have more room.
