WIO White Adder Boulder Nano Stone brings softness, pale contrast, and refined texture to your scape — rare miniature river boulders with cream-white strata, natural holes, and smooth layered crevices that evoke the character of Hakkai stones in pale-cream, delicate form.

White Adder Boulder Nano Stone is a rare, pale-toned sedimentary boulder shaped by time and water — featuring soft cream-to-yellow color gradients and an exceptionally rich surface. With natural holes, strata lines, and fine crevices, each piece echoes the look of traditional Hakkai stones in pale-cream, scaled perfectly for nano tanks and fine detail work.

Its smooth yet slightly rugged texture gently reflects light, creating a soft, tranquil ambiance that beautifully contrasts with green plants, moss, or darker stone elements. The subtle play of tone and form makes it ideal for serene biotopes, minimalist aquascapes, and terrariums that seek natural elegance. Sized under 10 cm, White Adder Boulder Nano Stones are pre-washed and ready to use. While generally stable, they may slightly raise water hardness over time — making them well-suited for alkaline-tolerant setups.
