ZAS Pro Seiryu Stone Aquascaping Sand (500g)

Just like a chipped tooth, glued-up joints on rocks and wood always sticks out like a sore thumb. No more hammering and smashing of your flooring, here's the resolution to fill up gaps as you cover them with glue.

Comes in 4 options: Seiryu, Dark Lava, Red Lava, and Mountain Stone.

P.S. Dark and Red Lava options make up a really natural joint between wood pieces =)
