Shown here are "skylights" that I had manufactured to display dark insulators better. They work the best in direct sunlight. I have featured two tiger striped B beehives that are NOT included. The skylights actually do bring out the colors to the naked eye, but only for a couple of hours each day when the sun is high in the sky in the exposure you are facing. Again the insulators shown are not included with the skylight. $15 each plus shipping.
