Glowing Egg-It by Celtic Blob

Celtic Blob:-

"  ✨  Glowing Egg-it

A fusion of fluorescent and phosphorescent fibres, giving your flies a subtle but eye-catching glow.  Soft, silky and easy to wrap thanks to its fine core, it creates a gentle halo in the water that adds depth and movement.

Perfect for eggs, blobs and streamers and at it's best when brushed out for extra volume and translucency.

Launching in eight fish-catching shades.

3M per pack."

MFF:-

As the name suggests - this extremely soft material has a glow effect.  The glow 'magic' happens when it is charged up in day light or using a UV torch.

This is got to be THE material of 2026!
