Robust 3D - Kids Glasses

Hello,
I have these 3D glasses children equal 2x ordered for my two sons.
The glasses are more stable than the usual cinema glasses and also look very chic made.
Whether they work in our theater, we unfortunately can not test.
With our 3D TV function properly. (We have the LG 55LM615S)
My sons are 7 and 3 years old.
Too bad that the glasses are not available even for small children because they do is a little too big for the 3-year.

Myself I have the glasses ordered because I have a small and narrow head ... but then, of course, in pink)

I would apply the negative product review will be deleted, this is about the quality of the product and not to the pros - and cons of the 3D process in children !!
Many Greetings
