These 4 delightful ornaments will add a twinkle to your Christmas tree. Used with incandescent Christmas lights, the fins in these ornaments will flash and add a sparkle to your tree. As is common with these ornaments, they show melting from being too close to larger, old fashioned Christmas lights. Two yellow spinners have melt marks at the bottom (see pictures). The pink star has a clouded spot near the bottom from the heat as well as one of the three yellow ones.
