If I have time tomorrow I'll try to dig mine out. I had a carrying case for my pogs. We were obsessed with 8 ball pogs. Which is funny to me since it was probably a cocaine reference but we just thought it was a billiards reference. But yes there were metal slammers and plastic ones. The plastic ones were triple the thickness I guess to make up for the weight... but they were still half the weight of the metallic ones. You were at a severe disadvantage not having a metal slammer.
