This is an set of 20 black hand-painted rocks featuring space scenes. They are perfect for an eco-friendly table confetti that can be reused, or you can give them to your guests as a party favor to commemorate your event. Great for a space science themed party or used for a scavenger hunt. Each stone design is different! All measure from approximately 1" to 2" in diameter and are painted with an enamel paint. They can endure most weather conditions. If you are looking for a custom order please expect a 1 week delay for paint to fully cure. Convo me for specifics. Thank you for looking at this item.
