Approximately 27x15mm bottle charms. These bulb-shaped clear glass jars have a 6mm neck opening. Lightweight. Includes a real cork (plain or with loop). Most corks fit snugly, but a few won't. If cork or loop come loose, a drop of superglue works wonders.Perfect to seed bead over, or fill with tiny beads/crystals. Tie onto cord and hang around your neck to hold medicine, prayers/affirmations, etc.
