Okay, this Hippolytusiart wind spinner is seriously mesmerizing to watch! The 13-inch spiral tail is made from quality 304 stainless steel that won't rust, and that 2-inch colored glass ball creates the most amazing optical illusion when it spins - it looks like the ball is floating and dancing in the air! The rainbow colors catch the sunlight beautifully and create little rainbows around your garden. Now, important note - this doesn't spin on its own because it's a bit heavy, so you'll need to attach it to a wind spinner base or a motor (not included) to get that beautiful rotation. But once you do, it's pure magic! The spiral also works as a stabilizer to keep your other wind spinners from swinging around too wildly. It comes beautifully packaged in a gift box, making it perfect for birthdays, Mother's Day, Christmas - anyone who loves garden decor would be thrilled to receive this. We've had ours hanging on the porch for months through all kinds of weather, and the colors haven't faded one bit. The quality is much better than those cheap painted ones you often see. If you want to add some movement and color to your garden that'll have all your neighbors asking where you got it, this spinning spiral is absolutely worth it!
