FAQ
Q1: What’s the difference between Standard and Voice-Control?
A: Voice-Control adds English & Chinese voice commands to open/close the gauntlet. Other effects (LED, pop-up laser, SFX) are the same.
Q2: Does it include batteries?
A: No. Please prepare 4×AA.
Q3: Left or Right hand?
A: Both are available. Select the hand option on the product page.
Q4: Is it suitable for kids?
A: It’s life-size and generally too large for children. Recommended for adult collectors/cosplay display.
Q5: Can I return it if the fit isn’t perfect?
A: Fit varies by palm size and thickness; please check notes above. If your goal is desktop/display, fit is not required. (Follow your shop’s actual return/exchange policy.)
Q6: The finish has tiny paint marks—normal?
A: Small paint specks, seams, or minor burrs can occur with hand-finished props and are within normal tolerances—not quality defects.

I use this MK50 helmet for cosplay, and it takes my Iron Man suit to the next level. The automatic faceplate opening and closing gets such a reaction at conventions—people literally stop me to ask where I got it. Comfortable to wear, super realistic, and the lights make it perfect for photos. A must-have for any serious cosplayer!
The shipping was super fast! The Iron Man MK50 transformation is absolutely amazing—both the voice control and touch control work perfectly. Closing the back panel with just a touch looks so cool! The way the helmet transforms around the sides and back of the head is simply stunning. Such a great collectible helmet toy—I love it!
As a lifelong Iron Man fan, this MK50 helmet is a dream come true. The attention to detail is spot-on, from the metallic finish to the light-up eyes. The voice command system makes me feel like Tony Stark himself. It’s not just a display piece—it’s pure fan magic!
Got this as a gift for a big kid—he couldn’t be happier! My only issue is that my head is too big to fit inside. The helmet has so many features that my son couldn’t remember all the voice commands at once, so he’s been playing with it while checking the manual. Looks awesome and it’s so much fun!
