Prototype Crished Opal Mobius/Circle (Signed) Binary Matrix with Bloom - 14mm

This was a prototype that was gifted (see signature pic). It has crushed opal sections between matrix percs, below mouthpiece, and for each arm holding logo disc. It is thicker than a production piece and is super solid. Please see pics: it has mineral/bloom build up in the stem, the lower section of the can, and ring in the upper section. You can where someone tried to use salt to clean it out, so the minerals are scratched in can - but I see no scratching in the stem, so assume it’s only the mineral build up that is impacted. It is 14mm but does not come with slide.
