Vintage MCM Rainbow glass optic decanter with ball stopper Amberina UV glow

Mcm Rainbow glass Optic decanter with bubble or ball shaped stopper in amberina / tangerine. Cadmium glow under UV light.

Stopper has Smooth stress crack. You can’t feel it. It is only visible from just the right angle on display.
Hard to see in pics because of reflection, but the crack runs vertically right through the middle of the part that sits inside the decanter. Zoom in to pics for best assessment.

Bottle has rough manufacturing flaw (pic 8)
