I ended up keeping 10 sets of each color block eruptor as i thought they would be a cool collectible later. Interested to see what these sell for!
Your saying you have 10 sets of each color? So 110 block erupters? If so that's insane.
It took me a few years to find a few of the colors. The silver one with the orange logo and orange one with white logo (both first batch without regulatory markings) were by far the hardest ones to find.
Oh yea, i used to flip these things back in the day on amazon. Would buy them here for around $10 to $15 a piece and then sell yhem on amazon for $50+ ea. Literally flipped thousands of them. I also bought them when they originally came out, but got all of the colors through the flipping technique.
