If you’re dressing as a character from the manga Yu-Gi-Oh! and want to up your game, this Duel Disk prop by CorSec Props could be what you’re looking for. This portable device from KaibaCorp in the game allows players to duel on the go. This replica prop fits over your forearm and glows with LED lighting. CorSec shared some information about the materials they used:
Finished this up today. Packing it for shipping. Its the new Duel Disk for Kaiba from Yugioh. I am in love with the way the lights came out. Most of the front part is blue fluorescent acrylic on top of a thin (2mm) layer of 3d printed natural PLA. The domes are the same PLA. The body is a mix of 3d printed and laser cut items. The cardholder is laser cut PETG that was airbrushed.
