Penn-Plax First Impressions

They are glass.

There has been no adverse effects from the rocks. One thing I can say is 200 pieces is only good for a 5 gallon tank. The price is a bit shocking at first, but the rocks are nice. 500 marbles isn't as big a bag as you think, but they're all there. Worked well for what I needed them for. 2 tanks have a betta or corydora catfish so I needed smooth rocks for their safety. Light casts through them well and they are attractive.

Penn-Plax Final Thoughts

Works well.

Nice and shiny giving that always wet look. So, very pretty, glow nicely at night and add a pop of color during the day. I ordered two packets and counted them one by one. Great quality, though smaller than I thought. I just rinsed them with hot, then cold water, and put them in the tank. These gems are so dainty and sparkly! Described as aquarium stones but I used them to decorate my plant pot.
