Got it for my 3 year old son he loved to build it and play. I would say I had to use fabric glue for the teeth. But we made a great coustum

My 4-year-old grandson loved it! He immediately started to make it, with the help of his Dad. They love to do that. They made it in time for him to wear at his birthday party! He's very good at putting things together.

It is an adorable mask. The chomping mouth was a little difficult to work. It was hard to adjust the screws to get it to chomp like in the video. In the end, it was OK because he just left it open.

It was a fun project and looks cool! The mouth doesn’t drop open easily tho so can’t really chomp as easily as you’d like.
