Usually, cosplay builder Gekidan makes helmets and armor. These are not usual times, and recently, he’s been making Gundam-themed masks.
When he ventured outside in the Mobile Suit Gundam mask, Gekidan used the hashtags #自作マスク (“self-made mask”) and #ウィルス対策 (“virus countermeasure”). Its design appears to be the most functional.
Gekidan isn’t only making Gundam themed masks. Here is a Getter Robo mask.
