This is God Eater 2 mini figure set by Bandai. Normally, this box is sold as is in shops and one wouldn't know what's in the box until he opens it. If you purchase the whole box though, you are guaranteed to get all 9 chibi figures.
Who you get are...
8. Emil von Strasbourg
9. Erina der Vogelweid
The chibi figures stand at about 6cm, give or take 1cm and each of them comes with its own lego-like acrylic little box which you can attach together via top & bottom.
It's a nice little bonus that you get these boxes, especially for those who don't plan to display them in a display unit or don't have a display unit to begin with. The box is sturdy enough to protect the figures from elements and pets.
The quality of the mini figures are fairly decent. For its size, I can forgive some painting faults, so I am not going to go into that. But I will mention that the head to body connection appears to be somewhat fragile. I feel like I could snap their heads off with little force.
Additionally, this is probably an isolated case but few figures had some sort of sticky residue.
Finally, this box can, at the moment at least, be purchased for about 30USD + shipping on Ebay.
