I have been buying those over the course, and finally completed the set! They are as big as nendoroids, some of them even have little props to hold onto. Altria has her blitz gun and Excalibur; Mary and Anne have their weapons; Tamamo no Mae has an umbrella and an extra pair of ears (the hat is completely removable like Martha’s)...
One thing I wish is their hand props can be set up easier, the umbrella and Mary’s gray sword are tricky to put on and they fall off easily. On the aspect of their paint job and sculpture, you simply get what you pay for. They are not amazing, but still worth collecting during the sales.
