The vintage-inspired typography and golden accents celebrate the mathematician’s world — pi, plotted functions, and a wink that says, “I have problems” with pride. It feels like a small, private trophy on a desk or a communal laugh in the math department lounge. Thick ceramic walls hold heat well; the C-handle sits comfortably in the hand as you stare at a screen full of proofs or scribble ideas on a notepad. Use it when the day demands focus, or when you want to share a smile with a colleague between classes or study sessions.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- Glossy 100% ceramic — black finish with vibrant, crisp print\u003cbr\u003e- Available in 11oz and 15oz sizes\u003cbr\u003e- Microwave- and dishwasher-safe for everyday use\u003cbr\u003e- C-shaped easy-grip handle — comfortable for long study sessions\u003cbr\u003e- Lead-, cadmium- and BPA-compliant; manufactured to safety standards\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Clean in dishwasher (put the product on top rack), or wash  by hand with warm water and dish soap\u003cbr\u003e","brand":"Printify","offers":[{"title":"11oz","offer_id":45420581945367,"sku":"27349364796783068967","price":15.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/5862\/7607\/files\/12793802203321590341_2048.jpg?v=1787194919","url":"https:\/\/shop.mathify.dev\/products\/mathematician-coffee-mug-of-course-i-have-problems-funny-math-gift-black-11oz-15oz","provider":"Mathify Shop","version":"1.0","type":"link"}
