Description

Big bricks for small hands

Duplo bricks are twice the size of classic bricks and much easier to grip and press together. That is exactly what this box is for. With 110 pieces you can make towers, walls and simple houses that even toddlers can build alone. The set came out in 2003 in the Explore line and is a plain starter stock. It needs nothing extra to work and slots neatly into an existing Duplo collection. Older siblings can join in and help as well.

Four clear primary colours

Red, green, yellow and blue are the four main colours. They are strong, easy to tell apart and ideal for sorting, counting and naming. Many parents use boxes like this to practise colours with their children or to lay out simple patterns, such as alternating red and blue. Because the colours are so distinct, you can tell from across the room how tall a tower has become and which bricks are still missing. Building quietly turns into a small colour game.

Ten shapes, plenty of repeats

With 110 pieces spread over only 10 different shapes, the set is clearly simple by design. The same bricks turn up again and again, so there are few surprises and little hunting around. That helps while building, because a needed brick is always close by. For small children this is an advantage, as nobody has to wait long for the right piece. The parts list on this page shows which shapes are included. There are no figures or special elements, so all the play comes from stacking and connecting the bricks.

Combining it with other boxes

The name gives it away: this is a half box that looks modest on its own but becomes valuable as an extension. More bricks mean larger and sturdier structures. The What can I build? tool shows which other Duplo sets you could rebuild from your stock. A collection grows step by step this way, and fewer pieces sit unused at the bottom of the toy box. Even second-hand, such a box is usually ready to play with again quickly.
