Puzzles & Building Blocks

Building blocks and jigsaw puzzles snap or slot together from loose pieces — no glue, no paint, no tools. The range here is led by Japanese micro-block systems, above all nanoblock from Kawada, whose smallest brick measures just 4 × 4 × 5 mm, alongside Ensky jigsaw puzzles and PUREMIND licensed brick sets.

How is this different from a model kit?

A scale model kit arrives as parts on sprues: you cut them free, glue them, and usually paint them. Building blocks and puzzles need none of that — pieces interlock straight from the box, so a set can be finished in an evening and taken apart again. If you want the cut-and-glue hobby instead, start from Model Kits; for ready-built display pieces, see Completed Models.

What you will find here

• nanoblock — Kawada's micro-block system, small enough to render curves that larger bricks can only suggest. Landmarks, animals, "Pokémon", "Dragon Ball" and character sets.
• Ensky jigsaw puzzles — anime and Studio Ghibli artwork, including clear and 3D formats.
• PUREMIND brick sets — licensed builds such as Snoopy and Dragon Ball scenes.
• Square Enix and TomyTec — game and vehicle block sets.
