Certified Girl Math Expert Clear plastic Tumbler
Stay hydrated and delusional with the Certified Girl Math Expert Clear Plastic Tumbler — the ultimate sippy cup for big adult financial theories, like “If I drink three $6 iced lattes at home in this tumbler, I’ve basically saved $500.”
This sleek, clear tumbler lets everyone know you’re not just sipping — you’re calculating. Whether it’s water, iced coffee, or the tears of your bank account, it holds 100% liquid and 0% judgment.
Features include:
A secure lid so your financial fantasies don’t spill
A reusable straw for sipping while you online shop “just to look”
Perfect for:
Mathing in style while you fill your cart and abandon it (for sport)
Saying “I needed this” about literally anything
Staying hydrated as you explain how a vacation booked with points is practically a business expense
This tumbler isn’t just a cup — it’s a hydrated lifestyle with questionable math logic.
Because in Girl Math, coffee in a cute cup is an investment. 💅🧃📊
