3D Wooden Puzzle-Model Building Kits-DIY Assembled Toys(Treasure Box)

The instructions are easy to follow, and it's relatively easy to build. There are extras of some of the more fragile pieces which is great, as I broke one of the small pins trying to assemble it. Don't skip on waxing the parts where it says to, otherwise the gears may not turn nicely. It took a few hours to build, and would be a great way to spend a rainy or snowy afternoon indoors!

I actually was eyeing the marble run first, but since I haven’t done any from this brand before, I figure I should start with something simpler. This is a very well thought out 3D puzzle, and the finished product looks exquisite. My problem is really with how hard it is to get some of the pieces in place. I mean I have very little grip strength, so the later steps where you have to wiggle and force a piece in place was very difficult. And the wooden pieces aren’t strong enough to withstand some hammering. Luckily, with the help of my 8 yr old toy hammer and my trusty tweezer, I manage to softly bang some of the edge in without damaging the wood too much. The instruction isn’t exactly crystal clear, took me a page or two in before realizing pieces with + sign next to them are extra pieces. And I was kind of hoping my lego/puzzle savvy 8 yr old could have enjoyed this project with me. Nope, he might be able to follow the instructions, but to build this thing, a child needs to be pretty advanced in manual dexterity. Anyway, it took me about 2-3 hours, mostly trying to figure out how to bang/wiggle things into place. There were a lot of doubts as to if the finished project would actually work or not. It did, and frustration aside, I am impressed with the design. Definitely worth it if you enjoy building this kind of puzzle. Now I am thinking about getting multiple others to build and gift, since you can hide trinket in there.

Great quality with no issues. Came as described.

Very cool build! Complex and satisfying. Beautiful and functional. Love that you can build and set your own lock. I’ve tried a few different 3-D puzzle companies and ROKR is the best. Great customer service!

My 16 year old loves this gift! It is a bit tedious and during assembly, the pieces have come apart, hence he used carpenter glue to assist the build. He loves it though, and is intrigued that there is a combination lock for it. A great gift!
