Writing on metal isn’t always a walk in the park – normal markers don’t tend to show up well, and they always seem to rub off too easily. Our steel pen, however, tells a different story. 

Made from a non-toxic and chloride-free formula, our Steel Marker Pen is ideal for writing, drawing, scribbling and marking on all types of metal surface. So, whether you’re creating a beautiful display or marking out an area that needs to be cut or welded, you can do so easily with help from our steel pen range.

Available in all sorts of sizes and colours, browse our Steel Marker Pen range below. You’re just moments away from creating a water-resistant masterpiece that simply needs a damp cloth and a light scrub to erase!

Our Incredible Metal Marker Formula 

If you’re familiar with other Rainbow Chalk products, then you’ll know just how much planning and compassion goes into making our formulas as safe and effective as can be. Our pens for metal continue to prove just that.  

All of our metal pens are made from a non-toxic, chloride-free formula; making them safe to use on all types of metal (both indoors and outdoors!). This safe formula also means that you can use these pens in enclosed spaces without having to worry about any nasty fumes or chemicals causing havoc.  

Your markings will be touch dry in as little as one minute, meaning you don’t have to tip-toe around your work in fear that you’ll ruin it. If you do want to erase your markings, however, you can simply do so by applying a damp cloth and giving the area a wipe. It’s that simple! 

When To Use Our Metal Pens 

To keep it short and sweet, our metal pens can be applied onto any metal surface for incredible results. Popular uses include creating artwork, lists, reminders, markings and so on. The possibilities are endless! 

One thing which you may not realise about our steel pens is that they can be used on extremely hot surfaces, making the marking process before cutting or welding hassle-free. Our metal pens leave no staining either, meaning you won’t ruin the appearance of your neatly cut metal when finished. 

Types of Metal Pens Available 

We’ve worked hard to ensure that our metal pens can be used in a whole range of different situations – as mentioned above. This has been made possible due to our attention to detail surrounding different sized nibs and colours. 

Here at Rainbow Chalk, you have the choice between three different shaped nibs: 5mm bullet, 5mm chisel and a broad 15mm. The nib you choose will depend on the type of marking you want to create (the bigger the nib, the bigger your marking will be!). The smaller bullet nib is ideal for markings which need a bit more precision.  

As well as different shaped nibs, we also have a huge variety of colours for you to choose from. No one said that writing on metal should be boring, which is why we’ve chosen a colour palette which will please everyone. From the standard blacks and greys right through to bright pinks and blues; why not purchase a multipack to benefit from all of the colours of the rainbow? 

No matter what size nib or colour you choose, all of our steel pens feature a valve activated ink flow mechanism. This means that you will have complete control of the ink flow at all times, saving room for any errors or messy situations. 

Need Replacement Nibs? No Problem 

Our metal pens are incredibly long-lasting, meaning you won’t have to worry about restocking them anytime soon. However, if you do need a replacement nib, then you can take comfort in knowing that these replacements are also available at Rainbow Chalk. 

Whether the old nib got damaged or you just want to start fresh, our replacement nibs start from as little as £1.75 per 5 pack and simply snap on to your current marker for an easy transition. We want you to get the most out of every last drop of ink, and our backup replacement nibs make this all possible for you!
