10909

LEGO set 10909, Heart Box, is a Duplo set released in 2020 within the Basic Set theme path. It contains 80 pieces, presents a free building assortment based around a heart-shaped box, and includes no figures.

Heart Box belongs to the open-ended side of Duplo, where large elements are used for simple handling and flexible building rather than for a fixed licensed scene. In the theme path “Duplo, Basic Set”, it is best understood as a general brick assortment with a heart motif as its visual focus.

Rebrickable lists 80 pieces and 0 figures for this set. There are no named characters, so the build experience depends on the bricks themselves: stacking, rearranging, sorting and making small creations. The set can also be combined naturally with other Duplo elements because it is not tied to one specific model.

Heart Box is mainly suited to hands-on play and basic building rather than display. For a collection, it functions as a supplementary Duplo box, useful for expanding available parts without adding a defined story setting. Compared with more narrative Duplo sets, it remains deliberately broad and adaptable.
