0.5 ounce bag of Premium Mini Yooperlites. Total weight is half an ounce. These are very small but very bright under uv. These are all naturally tumbled by glacier activity and being on a Lake Superior beach for thousands of years. All stones are natural and not broken by me. Most are rounded by the beach and a few are broken from the beach itself.
3 stones minimum in each bag. Some contain very very small stones and have 10 to 15 mini Yooperlites.
The 1st people to order get the brightest stones, but almost all of these are top notch Premium.
To see the fluorescent glow effect you must use longwave 365nm filtered uv light, also available at www.yooperlites.com
