I'm Not The Boss I'm The Teacher Stainless Steel Tumbler

Bright, slim, and cheerful — this 20 oz stainless steel tumbler keeps drinks at the ready while showcasing a playful, teacher-focused design. The glossy protective coating locks in vibrant pastels, watercolor textures, butterflies and uplifting lettering that reads like a private classroom shout-out. Lightweight and narrow enough to slide into backpack pockets or a car cup holder, it comes with a clear lid and metal straw for easy sipping between lessons and lesson planning. Use it for hot coffee in the morning or cold water through a long school day — it feels personal, lighthearted, and made for someone who teaches with color and care.
