These are the 99.5% pure titanium beer mugs manufactured and sold by AI PEI on Amazon. The double-walled and insulated mugs hold 450mL (15-ounces), come in five different colors, and are perfect for letting guests know you think you’re better than them because you won’t stop talking about your ridiculous $168 titanium beer mug. That’s right, they cost $168 apiece (plus $15 shipping!). Which is exactly why I just cast my own much more economical beer mug out of lead. “Wait, what?” *sipping foam off top* Don’t be jealous.
