Thank you for viewing! Instant purchase and no-comment purchase are welcome ^_^ The GAN330 keychain is a cool accessory and also comfortable to use as a speed cube toy. This small puzzle is packed with various innovations from GAN cubes. It's sure to become your companion. Adjustable to your liking If you feel the rotation is too heavy or too light, you can easily adjust it without disassembling the puzzle. Customize it to your liking. Honeycomb pattern on the contact surface The honeycomb pattern helps to distribute lubricant throughout the puzzle. This pattern makes the rotation smooth and stable. High-level internal structure Corner piece feet - With two structures, rounded triangles and angular triangles, it is very resistant to pivoting (twisting of parts, making the puzzle unsolvable). Edge piece feet - The edge piece feet have a triple structure, making them highly resistant to POP (parts coming off, causing the puzzle to fall apart).
