乗鞍ロック（1kgあたり）

The pieces arrived with a nice mix of sizes and shapes, so my aquarium scape looks natural instead of too uniform. The weight is consistent for the price, and they cleaned up easily with just a rinse.

I was worried the rocks would look too uniform, but each piece in the 5kg order has its own unique shape and coloring, which makes my aquascape look so natural. The weight is substantial, and they stack well without sharp edges. Exactly what I needed for a realistic riverbed look.

The texture on these rocks is fantastic — rough enough for my plecos to graze on, and they sit solidly in the substrate without shifting. Weight per kilo is generous, and even though the shape varies, every piece looks natural in the tank.
