This is a posable action figure from the figma series.
From the Good Smile Company website:
From "Fate/stay night [Unlimited Blade Works]" comes a new figma 2.0 of Rin Tohsaka, following on from the release of Saber.
Using the smooth yet posable joints of figma, you can act out a variety of different scenes.
Certain joints use drawer-type articulation allowing for much more exciting action poses.
She comes with a standard smiling face, a shouting face for combat as well as an embarrassed expression.
Optional parts include parts to display her in slippers, alternate arm parts showing her magus sigil and alternate hair parts to display her wearing her glasses.
Effect parts for the Gandr spell are also included!
An articulated figma stand is included, which allows various poses to be taken.
