i got this for my brother in law and he loved it. it did not come with the instructions on how to assemble it but it is easy to find them online. he built it without instructions and he said it took him less than 30 minutes to put it together. i have built a few of these puzzles my self and they are not too hard for adults. kids might need help with holding it together until the final steps.

We as a family really enjoy doikg these 3D crystal puzzles. its a challenge and thats what we like!!!

I bought this for my grandson who loves skulls he put it together pretty quickly and it looks really good

The skull can quickly and was in awesome shape and was easy to assemble and I would deffinitely buy it again and oh it looks awesome up on my mantle

my son was very engaged. took him a little longer to build. which was nice. the end product was cute and durable

I enjoy doing these puzzles.

Loved the puzzles, so much fun and planning on buying more for a hobby !! 10/10 recommend!!

looks pretty cool

It was a little tricky to put together - definitely not for my 9 year old son but very cool once it was together. I'm buying another one!

Not very easy and will exercise your brain.
