Clics builds with round discs that click into one another, and this Rollerbox is the brand's big starter pack. It holds 560 parts: 463 Clics building blocks and 97 accessories and stickers, together with the plans for the twenty models the 20 in 1 label on the box announces.
The box itself joins in the play. It has a lid and two large wheels, so a child pulls it across the room and puts everything back inside afterwards. With a set this size that saves a lot of loose pieces lying around.
The box states 4-12, a wide span that matches how the set works: a young child clicks loose discs together and makes up something to go with them, while a ten-year-old follows the plans and rebuilds the truck, the aeroplane or the figure shown on the box.
This is a birthday or St Nicholas present rather than an impulse buy. Because the same blocks serve both free building and the plans, the set stays usable as the child grows older.
