DMCLight Effects Floss Pack 8.7yd 6/Pkg, Fluorescent

Using a UV torch with a filter and rated closer to the lower standard UV range of 365nm (I do not have UV torches that are lower frequency than this as they are considered very specialist and require safety equipment to use without eye damage), all threads glow under UV, see my second picture. The purple and the blue are not as bright as the green, yellow and orange, but they never are under this frequency of light. Usually you need a lower frequency to really make those particular colours 'pop'.Also, the white thread is also glow in the dark, the last photo is purely lit up from this thread alone after being exposed to the UV torch for about 5 seconds. It does not glow for very long, but it looks really cool when it does glow. Thread feels as you'd expect from Polyester. Can't wait to add it to a project.

Arrived 21 days before due date. DMC Light Effects Floss Pack 6/Pkg Fluorescent 317WPK3. Value for money. Super quality of Thread that you expect from DMC. WOW day glow threads the colours e Really do stand out.I can't wait until I use them.

As always with DMC threads lovely quality. Arrived by date promised. Look forward to using them in the future.

very pleased with my order do you do Christmas colours

Nice

Got out the blacklight for my project to check them, and swing and a miss, these aren’t fluorescent.The Blue is not fluorescent at all, the Purple is as minimal as I’ve ever seen, and the Pink - while fluorescent - is bizarrely dark compared to the others (which is odd considering how pink tends to be a more reliable colour for fluorescing).Orange and Green are on par, Yellow slightly brighter than them.

fantastic colours...going to stitch a sugar skull with mine.

As expected. Will buy again.

Beautiful colours, thought they glowed in the dark but was wrong, that was my mistake
