These are perfect for fusion splice and pigtails applications. I’ve used these for years and never had an issue.

They work exactly as expected. I\'m impressed.

Great, as described!

Works as advertised.
Don't drop the bag as i did :-)

These sleeves worked great. They were packaged very well when delivered to me. Their transparent tube design made me easy to see the status of fiber. and they are strong enough to protect the fiber connection points. a pleasing shopping experience overall. will order again if needed.

I bought both the splice tray and the protection sleeve. The splice protection sleeves are used well with the fiber optic splice tray. They together protect the spliced fiber perfectly. It is a necessary and essential accessory when splicing fibers. Good to use and shipping fast, worthy to buy!
