The MGC 7x7 is YJ’s magnetic model from the MGC line, with moderate magnets and an edge length around 67.5–68 mm. The cube itself is commonly listed at about 198–200 g, so it feels stable in hand while still being quick enough for training.

Who it’s for

• For cubers who want a magnetic 7x7 for regular practice.
• For anyone who values stability and easier layer alignment on higher-order cubes.
• If you prefer ultra-compact, ultra-light 7x7s, this may feel a bit “bigger”.

Turning / control feel

• Magnetic alignment helps layers “snap” into place and reduces finger wandering on long solves.
• Moderate magnet strength: controlled, without feeling overly heavy.
• Like most 7x7s, it improves after a short break-in and a bit of lube.

Magnets & mechanism

• Magnets: yes (MGC 7x7 version).
• Adjustments: standard center-screw system; some sets include spare springs of different stiffness for fine-tuning.

Size, weight & materials

• Edge length: about 67.5–68 mm.
• Cube weight: about 198–200 g.
• Color: stickerless (colored plastic, no stickers).

Main pros

• Magnets add noticeable control on 7x7.
• Stable, confident in-hand feel.
• Strong price/performance in the magnetic 7x7 category.
• Often includes basic tuning extras.

Possible drawbacks

• Close to 68 mm, so it’s not the most compact 7x7.
• May want some lube and break-in out of the box.

How to use

• Solve with standard 7x7 methods (reduction or preferred big-cube approach).
• If it feels too fast/slow: adjust tension, optionally swap springs, add a small amount of lube.

Box & contents

• Commonly includes: cube, a tool (screwdriver/tension tool), spare springs and extra magnets; some packages also add a short guide or a stand.
• Gross packaged weight is often listed around 350 g.
