Tumbler - "Engineer Builds Legacy" 40oz Vacuum Thermal Tumbler

This 40oz vacuum thermal tumbler carries more than drinks — it carries purpose. Built from durable stainless steel with a secure, re-sealable lid and a comfortable handle, it holds long days and late study sessions. The design speaks to engineers who hustle: bold typography, technical motifs, and a warm, collegiate palette that feels like late-night labs, campus pride, and the satisfaction of solving a problem. It sits sturdy in hand, keeps your coffee hot through morning briefs, and preserves iced drinks for long site visits. The stainless-steel rim remains unprinted, giving it a refined, functional touch that matches the tumbler’s hardworking spirit.
