These WAYBER decorative pebbles are such an easy way to add some color and style to your home decor projects. You get a full 2 pounds (about 920 grams) of these colorful crystal stones - enough to fill about 2 cups or half a liter volume. They're made from natural raw stones that have been processed into these irregular shapes with nice, smooth edges. The colors are vibrant but natural-looking, and they won't fade over time which is important for long-term use. I've used similar stones for so many things - lining the bottom of my fish tank (they help keep the water clean and provide a nice environment for fish), adding decorative topping to my succulent plants (reduces water splashing when you water them), filling vases for floral arrangements, or even for craft projects and wedding decorations. They're non-toxic and safe, which is crucial for aquariums and plants. The variety of colors in the mix creates this beautiful, natural-looking display that catches the light nicely. They also work for crystal healing or chakra grids if you're into that sort of thing. The 2-pound bag is a good size - not so much that you're overwhelmed, but enough to cover a decent area. Just keep them away from really young kids who might try to eat them, and you're good to go. Such a simple way to add some natural beauty to your space.
