Suddenly, it all fits together.

A modern take on the jacks you might’ve played with as a kid, this puzzle is made of six notched brass bars that interlock in a delightfully brain-bending way. Each formation is handcrafted in Wisconsin and has just enough heft to make it a paperweight (we see you, stack of receipts) or a statement object on your shelf. If you’re feeling fidgety and/or up for a challenge, you can try your hand at taking it apart and piecing it back together—instructions are included in case you get stuck.
