Labeled as a 'construction kit', assembly and painting is required. About 16cm tall.
Lovely and elegant it is, international fans will be facing some difficulties in getting it unfortunately. It's a Wave direct-web limited merchandise, and the production seems to be based on the number of orders the company received, meaning no more production after the period of pre-order has ended.
Pre-order period is between February 25th and April 30th. Release date is late June. The price is 13,440 Yen (inclusive of tax).
