Very well made with fairly modest thickness. Excellent value.

I bought this as a gift, and he loved it. It is challenging to complete but worth the money. The quality is great, making it a very nice piece.

It's a very nice little box.....the puzzle solution is a bit uninspired since it only requires moving one side of the puzzle several times.

I loved playing this game as a child, now my children are enjoying playing it.

Fairly easy puzzle, but good for kids and beginner puzzlers.

This is a nice small coding puzzle. My kids love the challenge, and we appreciate that it is made of wood. I recommend it for kids who enjoy challenges and puzzles.

Great. Will keep for myself.

Karakuri in Japan is famous for their beautifully made, whimsical puzzle boxes. This box is simple, easy to put together (with a little glue) and works well - the pieces fir together just right. It also teaches you a major principle used in many complex boxes. The kit comes with no color, so looks very plain - I stained it 2 colors and made it look like a more expensive box. Kubiya sent the box in a timely fashion and was easy to deal with.

A very well made and beautiful wood puzzle. The solution was a bit simpler than I expected, but it is still a great display piece. Looks great amongst other wood puzzles. I would definitely recommend for puzzle enthusiasts.

My dad (who was an engineer for over 30 years) loved this gift. It was very unique. He started working on it right away.

Exactly as pictured and the family loved playing the game!

You can play it with just a few rings to match each child’s level, which makes it really flexible. I love the beautiful wooden case it comes with for storing all the pieces.

It's beautifully made and surprisingly tricky to solve. The pieces look easy to put back together, but it’s more challenging than it seems at first. I really like the minimalist, natural look of the wooden heart. I recommend it to anyone who loves a good puzzle or enjoys collecting beautiful objects.

Great backgammon board for a great price. It has become a favorite for my wife and me when we travel, thanks to its portability and quality. I highly recommend it for anyone who must have his backgammon on the go.

I'm surprised to be the first to review this beautiful puzzle. The puzzle is truly a work of art, and I'm so happy I own it. It's now placed on my world puzzle collection shelf so I can show everyone I know what an amazing puzzle I solved.
