*Slightly Imperfect* Spinning Base - 100mm Glass Concave Lens - Pack of Two

*Slightly Imperfect* 100mm (approx 4") - Double Concave Fused Silica Glass Optical Lens - Thickness 0.4” (10mm) - Pack of Two

Our "almost perfect" might be just perfect for you! We have VERY high standards at Bruce Charles Designs, so when we carefully inspect each product, we sometimes find slight imperfections that cause us to set it aside.

These 100mm glass lenses have a very slight fogging or clouding inside the lens. This is hardly noticeable when using the lens on a tabletop or surface, but can sometimes be visible when holding the lens up to the light.. 

Please note: These Slightly Imperfect 100mm glass lenses are only available in a pack of two and will be shipped well-protected in bubble wrap and generic packaging. These will not be packaged in our signature black BCD gift boxes.

The function of these *Slightly Imperfect* items is exactly as you'd expect from Bruce Charles Designs - profoundly enjoyable and satisfying!

Don't miss this opportunity to grab these items at a great price!
