Ghostbusters “Slimer” mask

This mask was only available via a 48-hour pre-sale November 14th-16th, 2020.

The Slimer mask reappeared during a sale in February 2021; however, the few people that managed to snag one received the bizarre “Slimer Grin” mask instead (shown in the second picture). It is believed that this was due to an error in the fulfillment warehouse, as it has not been confirmed whether this mask is an actual RSVLTS release (the design on the mask is different in both the sizing and the lack of a bridge support).
