Penrose Triangle Mug
Start your day with a paradox.
This ceramic mug features the iconic Penrose Triangle, an impossible geometric figure that challenges depth and perspective. At first glance it appears simple, but the longer you look, the more the illusion reveals its visual contradiction.
Blending mathematics, optical illusion, and minimalist design, this piece transforms an everyday object into a small conversation starter—perfect for designers, programmers, artists, mathematicians, or anyone who appreciates clever geometry.
Available in 11, 15 and 20oz sizes, with a durable finish and vibrant long-lasting print.
