Let me start by saying that if you're into aquascaping, these dragon stones are a decent option, especially for smaller tanks or nano terrariums. I used them in my 20-gallon long aquarium, and while they didn't blow me away, they got the job done.
The good: You get a LOT of rocks for the price. At 18.1 pounds, it's way more than what most sellers offer for similar prices. The size range (2.1 to 7.2 inches) is accurate, though don't expect many large pieces - most are in the 5-inch or under category.
Be prepared for some work though! These stones arrive super dusty (like seriously, wear a mask when unpacking). You'll need to soak and scrub them thoroughly. Pro tip: use wooden skewers to clean out all those beautiful holes - it's tedious but makes a huge difference in the final look.
The not-so-good: About 3 pounds of my order was basically dust and tiny fragments (great for covering glue joints though!). Also, many stones are quite thin - not ideal if you're looking for chunky centerpiece rocks.
Final verdict? Great value if you need lots of small-to-medium stones for multiple small projects. But if you're scaping a large tank and need substantial pieces, you might want to look elsewhere or be prepared to get creative with stacking thinner pieces.
