Den learns by doing. So will you.

A living room floor at the end of an afternoon: an arch standing, counters in a tray, a dinosaur on its side, a child mid-reach.

The catalogue

Eight things to do with your hands.

Building sets that stand up, sorting work that a one year old can carry, and a herd of dinosaurs for the half of childhood that is not about learning anything.

Every set is printed after you order it, in Full, Natural or Monochrome, and nothing in the range has a part under 40 mm.

Den comes in the box. One card, one story, and one thing to try with the set before anybody reads the instructions.

Every number here is off the drawing rather than off a finished toy. The one rule that is not a target is the 40 mm floor on any part, which clears the small-parts cylinder and does not move.

Made to order

Pick the colour world and we print it.

Send the code and the world you want. If you are buying for a particular age, say the age: it changes which set we would send you to, and sometimes we will talk you out of the bigger one.
