I recently started collecting puzzles and playing cards as an adult, and one brand I keep noticing is theory11. I was first drawn to their Lord of the Rings puzzle because of its impressive design, and later discovered they also produce exceptional playing cards. As a brand, theory11 specializes in crafting unique artwork inspired by popular franchises. Each product features a faithful design that feels both intricate and substantial.
Since I prefer to buy items when they're on sale, I hadn't purchased any theory11 puzzles or playing cards until now. With these collector's items discounted for the first time during Prime Day, I finally decided to buy the puzzle that initially caught my attention. Below, you'll find everything currently available in this sale.

The current sale features options from four popular fandoms. The Lord of the Rings and Harry Potter puzzles stand out as my top choices due to their book-like aesthetic.

Characters and subtle easter eggs from these beloved stories are thoughtfully integrated throughout the card designs.
