Size comparison with a cigarette pack

The frame articulation is, as expected, top-of-the-line.

The Valkyria Blade can be securely locked onto the underside of the shield via a slide mechanism.

You can also rotate the mounting section.

There is a peg on the blade's handle for securing it, but...

Plugging the peg into the palm does give a solid grip, but...
...as you can see in the arrow photo above, the holding angle ends up rotated 90 degrees, which looks pretty awkward.
On the other hand, you can just ignore the peg and have the hand hold it naturally in line with the fingers — that looks much more natural. (top)
In fact, even the official sample photos show it held parallel to the hand like that.
It really seems like a design mistake where the peg was put in the wrong orientation.. ;;

It can also be stored on the rear skirt.

Since the handle peg locks into the palm, the grip is very secure.

Only two hand types are included — an open hand and a weapon-holding hand — and since there's only one back-of-hand cover part, you have to tediously swap it back and forth.
It would've been so much easier if they'd just included duplicates, but every now and then they can be a bit stingy like this..

Sphere sensor open.
Look closely and you'll see the ball-shaped sphere sensor can actually be moved as well.

The cylinder at the back of the waist is reproduced as a moving part, though it's in a spot that's hard to see. -_-

Joint parts for mounting on Action Base 1.

Even with the armor on, the articulation is excellent.

That said, the large shoulders do make it a bit tricky to raise the arms out to the sides.

The side skirts move in two stages, so they don't get in the way of the legs.
