edding 8280 securitas uv marker - colourless - 1 pen - round nib 1.5-3 mm - black light marker - for hidden markings on almost any material - security marker, invisible ink pen, magic pen, geocaching

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

I recently purchased the Edding 8280 Securitas UV Marker, and it's proven to be a surprisingly useful tool. The invisible ink is truly undetectable under normal light, but reveals a bright blue glow under a UV light, exactly as advertised. I've been using it to discreetly mark valuable items and documents, giving me an added layer of security. The fine tip allows for precise marking, and the ink dries quickly. It's a simple, yet effective way to add an extra layer of protection. I appreciate the peace of mind this little marker provides.

Works as expected, which was a relief after seeing comments about dried out pens. While it leaves a mark, it's really only visible if you know to look for it which is basically the case for anything marker like this.Only negative ding (may be a seller or shipper issue?) was because it took way too long to arrive, seemed to take 4-5 weeks after ordering and that's with Prime!

This UV marker is great. I use it to mark certain items to help ID them in the event they were stolen. This could be used to secretly mark expensive items or simple things like office items that are prone to appear on someone else’s desk. Shine a black light on them and your mark will shine brightly! It sounds like I’m paranoid but it does work.

Seems to be working!I used it on the inside of my atrium home to keep birds from crashing into the big windows

I ordered five different UV Pens so that I could compare them. This one stands out above all the others as producing the brightest UV markings.As a result, I have purchased as second one.BTW - The company that shipped me this pen sent it quickly and without any problems.

Good

I tested this pen and while the ink is invisible to the naked eye, it does flueresce as expected when exposed to UV light. So that part is good. However after writing my name on back of my iPhone (on the aluminium case of the iPhone itself) and letting it dry for couple of days, I was able to remove the writing just by wiping it with a paper towel. So the ink is not of a "permanent marker" type.Another issue people should know about (not stated on the description page for this item currently) is that even if you order this using Amazon Prime, it is not eligible for return. Amazon says that "For safety reasons, items containing flammable liquids or gases can’t be returned to Amazon. For more information or help, please contact us."

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.

Fonctionne très bien et à bon prix

Diesen Stift habe ich gleich auf unserer Toiletten-Spültaste getestet. Ich bin sehr beeindruckt: man sieht den Stift ohne UV-Licht wirklich nicht, nur auf sehr glatten Flächen kann man - bei gewissem Lichteinfallwinkel - eine hauchdünne transparente "Lackschicht" erkennen. Das aber auch nur, wenn man weiß, wo man geschrieben hat; zufällig wird das niemand entdecken! Der Stift riecht beim Schreiben gut nach Lösungsmitteln, wie alle Edding-Stifte, unter UV-Licht leuchtet der geschriebene Text sehr hell auf. Ich bin derart begeistert, dass ich mit diesem Stift gleich Hinweise für einen Nacht-Cache geschrieben habe, den die Cacher bisher gut finden konnten - der Stift hat sich also bewährt. Jedoch braucht man natürlich auch eine gute UV-Lampe, ansonsten nützt der beste Stift nix!Fazit: Für Cacher-Kolleschen (^^) sehr sinnvoll!

I buy these pens every year and they're great for purpose. You can draw anything on a white wall and you only see it when uvlights are on. GREAT for Halloween house parties. Bought box of 10 and drew scenes on every wall in 20 x 12' living room. Oh.. and u can smudge them a bit too! Great fun

L’articolo è arrivato due giorni prima del previsto. Esattamente quello che cercavo!! È magnifico veramente, ne sono entusiasta. È completamente trasparente alla vista normale e con la luce uv si vede benissimo la scritta! L’ho preso per un progetto di modellismo, se riesco farò vedere il risultato finale del progetto, ma ci vorranno settimane. Si può usare in mille modi, sia per scritte semplici, che con stencil particolari, la distribuzione del colore è rapida ed assolutamente uniforme e piena! Soddisfattissima A+++ grazie al venditore
