"Thank you to the seller."

Overall, a great natural-looking stone in an aquarium. If you are thinking about buying these, DO IT. I may have even used too much rock but I love how the scape came out with this rock. The rocks were REALLY dusty, covers with a lot of clay. Not bad at all for twenty bucks total. Dragon stone has a nice reddish tone to it so it really stands out. I got six, nice sized chunks of slate.

Marina A987 Final Thoughts

"Im very happy."

The edges of holes are also sharp, but easy enough to smooth with a razor knife. Not sure why but I just expected more. The water deactivates it and makes it safe. I switched up my plans a bit and everything was lovely. You should never buy rocks but there's no Dragon stone down by the river. Provides an interesting texture to your aquascape. I had to break up some of the larger ones to fit what I was looking for.

These are just what I needed to creat stone walks in my model railroad park. Also, if you need any manzanita or any other driftwood. So glad I bought these for my tank.

"Exactly as described."

I wanted a dark rock decoration for my 5 gallon. The bag I received was 17lbs and the rocks were in good condition. They are the perfect little hideaways for them! Truly something unique that will appeal to any aquarist. These glow very brightly and are super light weight. Trying shipping this much heavy stone. Cleaned the dust and clay residue off under running water and some brushing.

"Very pleased with it."

Recieved 8 pieces of stone in my order with minimal chipping. They fit perfectly in my ten gallon aquarium. The resin color is dark, so no repainting needed. I soaked the rocks for about 20-25 min, took them out and hosed them off really well. After playing with them for awhile now. My cichlid love hiding under the caves. I purchased these for decor for my aquarium and I adore how they turned out.

"I bought 2 for a 2."

I wanted real stone instead of the fake stuff at the local box stores. They are making these by sloshing resin around in a mold, so it's really thin.

I use it in my resin art work and it looks fantastic! Shipping was very fast and even came early. Super happy with what, only downside is I should've bought 2.

"The grey or black."

It was plenty for the tank I wanted to scape. Cleaned the dust and clay residue off under running water and some brushing. I will not be able to get all 7 rocks in my Bio Orb 8 gallon tank. Not sure why but I just expected more. Photo 3 is during a diluted muriatic acid bath. It took about a hour to clean the rocks off. The resin color is dark, so no repainting needed.

For an Iwagumi layout, this would be the Oyaishi. Just trying to help you find good products for a good price. Different shapes and sizes to work with. For the price, this should be solid resin. Loved what I got, highly reccomend these. I may have even used too much rock but I love how the scape came out with this rock. For an Iwagumi layout, this would be the Oyaishi.
