edding 8280 Securitas UV Marker PK1

I've gotten hooked on escape rooms recently and managed to get my youngest son into them too - so this Christmas, he's asked that we create a home escape room. And, as anyone who has done one before would know, invisible ink can often be a part of these experiences.Knowing that Edding is a really good brand, I opted to buy this pen over cheaper alternatives and I was not disappointed. I've used it on a variety of materials in different colours and it's been fantastic. For those who have said that you can see the ink after writing, well yes you can. Because the ink isn't instantly dry. Give it some time (a few minutes is good, longer is best) and you will not be able to see it - especially on paper.I tested it out on my black faux leather phone case by drawing an asterisk and if I study it really hard in bright light I can just about make out the markings, but it's not immediately obvious at all and if you're not looking specifically for it, you wouldn't see it at all.Under black light, it's clear and bold - the pen writes as well as any other marker and is perfect for my burgeoning escape room. But as a tool for marking your property as a security measure? Also perfect. I'd caution against cheaper random-named brands and stump up a fiver for this one because you will definitely get what you need from it.

Superb. Used it on everything apart from the kitchen sink or toilet. Writing is super bright under uv lighting but you really cant see it when its dry.Great item.

It works but you can still see it on marked materials in normal bright light.

The edding 8280 UV marker writes clearly (under UV light) and dries fast. Great for marking valuables or documents discreetly. Ink is truly invisible in normal light and lasts well. A solid choice for basic security marking.

An excellent product. Got it to mark my husband’s power tools and it didn’t disappoint. Would definitely recommend.

UV marking is an essential for costly items in the halls of residence at Uni - it's in the rules that we have to do it.I researched the UV pens and the Edding was consistently mentioned.Yes it is more expensive but it is a wide diameter and seems to have a high ink capacity. Using my UV nail curing "torch" it really did show up my name on things like my laptop. If you look carefully you can just see the letterring by daylight - so its best used on the underside of expensive kit.Edding says the lettering should last 2 years in sunlight.So I'm happy - and hope it deters !

Dries fast. Tagged batteries, tools, other bits of kit and equipment.Excellent quality Shows up under black light, very bright and clear.Worth every penny on a security purpose.

An expensive pen to discreetly mark items that becomes clearly apparent when shining 365nm UV light over it. 395nm UV light will also do the job but 365nm UV light is just better although more dangerous if you misuse it.Tested the pen on shiny/glossy black plastic and (after several weeks) marks never become "invisible" (and remained obvious) under normal light.Also applied on rubber, which absorbed the pen but didnt really provide much benefit using UV light (probably needs multiple layers to remain persistent).Didn't attempt a rub test for durability (yet, will update this review if it proves an issue on black plastic).Overall, it works to mark items that becomes more obvious under UV light, BUT its performance appears to vary depending upon material is it applied to.

UV pen ink is very bright when shined with a uv light. Ink dries fast, and is pretty much invisible.

Exactamente lo que se espera de él. A simple vista no se ve nada y con luz uv aparece todo.Recomiendo escribir con la luz UV encendida.

Marker works great and is easy to use.

Be aware of that some materials require more than one application, and you might have to make a fixture or similar to get all of them in the same place. I would appreciate info about what solvent to use if the tip goes dry if the pen goes dry. This could happen if you forget to put on cap after use. My summary is: I wouldn't hesitate to buy these pens again!
