Puzzle Box 004 trick opening

Description

A trick opening puzzle box with two keys and no keyhole. They keys are numbered 041 & 042. Is it some sort of code?

Another in the series of puzzle boxes designed by Jürgen Reiche at Seibenstein-Spiele. Box 002 & 003 are also available. From initial assessment, it appears that this puzzle is about the same level of difficulty as the 003 although an entirely different and unrelated puzzling element.

Brian really enjoyed this puzzle. Particularly the art of misdirection used. To our knowledge, we don’t know of a commercial puzzle on the market at present using this technique.
We’re not able to say too much without spoiling the puzzle but Brian also appreciated finding a nice final step to reset the puzzle to exactly how you found it.

Size: 105mm x 105mm x 66mm. The space inside is restricted by the size of the opening of the bottom panel. Opening: 70mm x 20mm It does not slide all the way across. If you put something too large inside it could interfere with the mechanism. We don’t want to say too much more because that could be a *spoiler* but we’re not recommending this puzzle as a gift box unless you’re just putting something very small like a ring or small rolled-up money with a rubber band around it inside. But a credit or gift card will interfere with the mechanism.

A quality product made by Seibenstein-Spiele at their workshops in Münster, Germany from laser-cut plywood. Some puzzles have either a blonde wood top or a brown wood top.  The exact wood used for both the top and the side varies a little. Sometimes Jürgen has used plain brown wood like Bubinga and for others, he’s used wood with a streakier grain as you see on the sides of the one in the photo.  For the rest of the puzzle, Jürgen has used mixed coloured woods for the panels and the keys so the puzzle you receive will have the colour configuration you choose on top but the keys may vary slightly from the photos.
Choose either blonde wood or brown wood top from the drop-down box. 

The solution is included with the puzzle.  It was done especially in English with photo and words by Brian Young @ Mr Puzzle.
