Glass Butterfly Wing Slides (6pc set)

Clearly, just the thing

They are perfectly transparent.

Perfect!

This made all the difference with spreading wings! They're thick enough to weigh down the wings and no sharp edges to worry about. I've been struggling to spread lepidoptera wings without scales rubbing off on the glassine paper. Using these slides has made it a simpler, more enjoyable process. Highly recommended if you're a beginner hobbyist like me.
