AVAILABLE IN 5-LB BAGS: Non-polished glass marbles -- flat bottom with a rounded top. Oval and circular in shape. Commonly used to fill vases and mason jars; as decorations placed at the bottom of aquariums and birdbaths; for creating magnets and other DIY crafts and jewelry; as well as quick party favors at weddings and other formal/non-formal events. CHEAPER THAN HOBBY STONES: Though these gems produce no residue, washing them before use will remove any dust or grime collected onto the glass during shipment to get the more sparkle and shine. Each glass gem is approximately ¾" in size -- roughly the size of a nickel. Marbles act as wonderful weighted filler for stabilizing and supporting cut flowers, tea lights, makeup brush containers, kitchen utensils, table centerpieces, and other top-heavy items. QUALITY WEIGHTED BASE OPTION: Attractive looking, sized right for filling various containers, and shipped in manufacturing quality. These gems are especially great for top-heavy vases, where you do not want too much added color to distract from the flowers nor interfere with the placement of the stems. A very attractive and cost effective decorative accessory. ILLUMINATES WHEN EXPOSED TO LIGHT: With proper care, these gems will last an entire lifetime. The translucency of each gem allows any light source to shine through, creating beautiful illumination you will love gazing upon. Scatter a layer onto the base of a birdbath to let birds and bees take sips of water without risking drowning. A DECORATIVE MARVEL IN MARBLES: These ornamental marbles are just the embellishment you need. Use them for your DIY projects such as filling your flower vase, fish tank, or votive candle holders. Purpose them for wedding favors, birdbaths, magnets, and more.
