This is a double-chambered mug. The outer chamber is a diving bell helmet with a ventilator and hose sculpted over the face port, and the inner chamber is an octopus tentacle. This was a numbered maximum run of 250, and was released as a pre-sale in July of 2020. Shipping began in early 2021.
The mug shipped with a small switchable pendant LED to provide a lit effect in the helmet, and with a double-ended barspoon/trident fork.
