Cardcaptor Sakura Clow Wand / Sealing Staff (Re-Release) (2015) (Movic)
Movic is re-releasing the clow wand in 2015, in a 1 : 1 replica. A similar wand would be the original early release edition of 1:1 clow wand, which contains a metallic clow key.
No particular electronics components are observed at the moment.
Notes: Personally i would prefer Proplica did a replica of the original clow wand, similar to what they had done with the Sailormoon wand & rod, with the full electronics component to create the original effects.
