AZIMOM PMMA Plastic 550pcs*0.03in*13.1ft Fiber Optic Cable Strands 0.75mm 4 Meter End Glow Roll Fiber String for Star Sky Roof Ceiling Decoration All Kind LED Light Engine Driver

Fibers help up through install and emitted light as expected, no issues with brittle quality and breakage.

This moves quite a bit of light. It's important to get the light source and fiber end lined up.Keep it coiled- the cladding will break if you bend it too sharply at a point.If you cut this- you might need/want to polish the cut end. I had pretty good luck by cutting at a small angle and using wet/dry paper wet. Mostly, I just use the full length and coil it.

I will be using them in conjunction with epoxy crafts. Size, light transmission, and length are perfect for my needs.

Great item!!!!

Leaves the installation to your imagination.

These are great and come in handy for my next build.

Do not trust this product. Fibers are inconsistent sizes.

I recently ordered fiber optic lights for my truck. Upon install I realized I needed around 100 more that were the same length. So I went with these and it was exactly what I ordered.
