They look interesting but i tend to not buy home made products. Anyone know if these are official or not? Or own these?

They do not look like any official item I am aware of. Could be, but I doubt it.

Issues I see with them being official:
one is a picture of a toy
one looks to be a pic from the WildStorm comics
Mumm-Ra The Ever Living is really mummy form
Mumm-Ra (mummy form) is really Ever Living form
Too wide of a range of original cartoon with new stuff (shots from cartoon with Cat's head X-ray)

Not official merchandise.

I won't count them as official either, still some of them are really nice-looking ;)

All those butoons are custom made. I bought some a couple of years back. Very nice and great quality.
