Selling a Silver Streak Lava Lite lamp

[Thomas Austin]

Hello! I just wanted to post this vintage Silver Streak I have for sale. It's clear liquid with yellow/white lava. I think it may be custom? Looking to sell it for $50 + $20 shipping, although I'm willing to negotiate. Dated February 10th 1997. The cap is not the original one, so it isn't a perfect fit.
