Sip with rhythm and precision. This 15oz stainless steel tumbler is built for the tempo of real life, steady, reliable, and tuned to perform. Its double-wall insulation keeps your drink hot or cold for hours while the ergonomic handle and leak-proof lid ensure every movement stays clean and controlled.
Available in white, navy blue, and black, each tumbler carries Brassline’s signature gold trumpet emblem, a refined nod to the brand’s musical roots. Whether you are heading to rehearsal, the studio, or a slow morning at home, it holds your brew like an instrument holds its tone, confident and clear.
