The Mastermorphix (also known as the Master Pyramorphix) is a 3x3 morphix shape modification. This twisty puzzle is shaped like a pyramid and comes with an instruction manual. It's also stickerless, meaning the sides feature separate colored plastic pieces, so no stickers are needed. The center piece uses a new assembly, directly concealing the center base within the internal components for better symmetry. The split cover design on the inner floor of the edge allows for more stable assembly, effectively ensuring the puzzle's smoothness. Great for adults to help prevent memory decline. This classic puzzle game will never go out of style and keeps your kids away from TV/iPad. Widened rounded corners ensure a sleek look and greatly increase corner cutting. At the same time, 36mm inner rounded corners improve POP strength, reduce corner twisting, equalize rotation resistance, and balance feel and functionality. This particular variant features vibrant, stickerless pieces. It's factory-lubricated and performs excellently right out of the box. The 3x3 Mastermorphix Stickerless Magic Cube features a .77.5mm size and a new curved surface design, providing better grip and unparalleled color brilliance. ULTIMATE GIFT - The ultimate gift for kids, friends, family members, beginners, and professionals. Provides hours of enjoyable play. Perfect for reducing stress, exercising the brain, improving patience, memory, and practicing practical dexterity and mental skills.
