5004936 Iconic Cave is currently free with purchases over £25/30€/$50 at shop.LEGO.com.
This one, however, contains two minifigs, both of which are unique to it, rather than being straight copies of collectable minifigures.
The packaging is almost as important as what's inside it, so let's take a closer look.
The sleeve is slipped off to reveal the cave-shaped box.
The box is printed with some cool decorations: brick-built heart above the door, washing hanging out to dry, and a lost dinosaur poster round the back.
Perforations around the door allow it to be opened to expose the inhabitants.
They come pre-assembled (what a boring job that must be for someone in China!) and are held in place with a plastic tray. They are actually quite difficult to remove.
They are both printed with typical caveman attire and armed with clubs.
The female has back printing, the male not.
The male in this set has a similar, but not exactly the same, print design, while the that on the female's torso and legs appears to be identical to the CMF's.
However, both are printed in different colours, and they have different colour hair, as is plain to see.
Overall, then, this is great gift with purchase which is available for a low spending threshold. The box is great -- almost too good to open -- and the figures superb. They are particularly desirable if you don't have the CMF versions.
You have until the end of August, or while stocks last, to acquire it, so if you haven't already secured yours, place an order today:
