This information came from the Sakura of America website, but the information is great, so I have replicated it here, hopefully the more you know the more it helps look after your pens. (Note though – I have had success with putting Gelly rolls in hot water for a short while to get them going again – so it maybe depends on the cause of the fault. I have had success with unclogging a micron with use of dipping it in rubbing alcohol – you can buy a wee bottle at your local chemist.)

Gelly Roll Pen Care
Gel inks need to be kept sealed away from air so it is very important to put the correct cap on the pen between uses because unlike regular ballpoint pen ink, prolonged exposure to air will cause the gel ink to dry-out in the tip/ball chamber. (removing the barrel end plug will have the same effect)

In our Gelly Roll ink system there is a tiny silicone ball inside the cap that touches the tip and helps prevents any air from drying out the gel in the ball chamber when the cap is on. If this silicone ball is damaged or removed, the pen will eventually dry out and not work.

Gelly Roll can be stored horizontally or vertically because of the properties of gel ink. If you choose to store them vertically, just be sure that you don’t drop them into the pen cup as this can cause air bubbles to form in the gel, which will disrupt the ink flow.

The best way to see if a Gelly Roll pen can be revived is to scribble in circles and/or firmly tap the tip of the pen on a pad of paper. The motion makes the tip (ball) roll and causes the gel ink to be pulled into the ball tip chamber. It might take a few tries, but may help to revive the pen. There is no guarantee though that this will start the pen again. Heating a Gelly Roll tip or shaking the pen will not correct the problem of a clogged nib. This technique only works for oil-based ballpoint pens.

Micron Pen Care
Micron’s best use is on paper, so be aware that alternative surfaces may contribute to a bent or clogged nib.

Why is my Micron nib getting clogged?
A Micron nib may clog from use with partially dried paint or primer, wood dust, fabric dust, starches and protections on fabric surfaces and very fibrous paper. Micron nibs are small plastic tubes which allow our pigment ink formula to easily flow from the barrel to the paper. When any foreign matter clogs these tubes, the Pigma ink flow is blocked.

Why is my Micron nib so delicate?
Microns are designed to be used at a 90° degree angle. The smaller point sizes (003, 005 and 01) use very delicate nibs to create the extra fine line, so they need to be used with a very light touch, no more than the weight of the pen itself. Microns require very little pressure to provide a flow of ink. If you experience a bent nib, switching to a thicker nib size, and/or using lighter hand pressure when writing, should resolve the issue. Our Gelly Roll or Pigma Micron PN pens provide an alternative for a more durable point and are ideally suited for everyday writing use.

Why is my Micron leaking?
A leak near the nib holder or ink wick could be caused by dropping, inadvertently shaking, or accidently applying centrifugal force to the pen by spinning it in your hand. Be sure to handle your Microns with care to prevent leaks from happening.

Why did my Micron pen run out?
Although Sakura strives to make a durable Pigma product, it is considered a “disposable pen”. Our standard product performance is based on a 24 month shelf life. Most of our Pigma products can last longer than the 24 months (with the exception of running out of ink or damage to the nib) under ideal use conditions.

Take a moment and a little space for yourself and pick up a tile your favourite tangling pen and enjoy tangling with your favourite tangle!

The Zentangle Method is about reducing the decision making to make it easier to flow, and therefore  ‘relax’ as you are drawing.  Concentrating your focus on one elemental line, where it is going, here and now,  not worrying about the outcome or the bigger picture. 

However, one thing starts to come up, people love a little colour in their life – and in their tangling.  So once you have got confident with some tangles, have mastered some shading techniques, and are happy using tangling as a relaxing tool, the next stage is often that you want to add a little colour to them.. Maybe you want to decorate a gift tag or make a card, something with an end product in mind, and up comes the idea of adding colour…

When I am teaching about adding colour to tangles, I will often say to stick to the method, but there are certain tools which I would say are helpful to tanglers who want to add some colour easily.

For beginners, If you are not so confident with adding colour, or this is your first foray into adding it, I would recommend buying yourself a set of watercolour pencils (a set of 12 is plenty) this means you can add lots of depth of colour by applying a little colour with a ‘dry’ pencil and then using a fine brush with some water to  ‘blend’ out the colour. An easy method to play with, treating your brush as if it’s the tortillon.  If you then add the coloured pencil to a ‘wet’ surface it acts more like paint/ ink, so you can get a deeper colour. (Bonus the archival ink pens won’t bleed with the water.)

If you are blending and using colour with normal coloured pencils you will find they are near impossible to blend with a tortillon or a stump, even high waxy content ones, as neither of these paper based products is an ideal tool for the hard pigment/ wax/ binding agent or additives they contain.   So instead I recommend using a colourless blending pencil for normal coloured pencils, you can also use a white – but note if working with dark shades, it will (obviously) lighten them a wee bit..

However if using a chalk or soft pastel coloured pencil (they are powdery and are made of pure mineral pigments,) you can blend with a tortillon or a stump. The issue here is often having lots of different blending tortillons or stumps for each colour, so you spend your time constantly changing, or mixing your colours on the tool. (Why often I have a collection of purple ones). So keep these tortillons like a set of coloured pencils. Note – the finished art will need a fixative.

Using coloured gelly pens, this can be pretty effective at adding highlights, and they work brilliantly on black and coloured tiles. The Gelly pen Metallic or Moonlight ranges from Sakura are perfect for this with their vivid colours and white. Reduce your decision making by limiting your colours, you only need a few to be very effective.. Or use these gelly rolls instead of your black pen.

Paper washes, if you want to have all the colour in your prep – then use some inks or watercolours to preload the colour on your tile before you even start to tangle – you can use the different colours as if they were your string. – Yup, keep to the method as much as you can to make it easier for yourself.  There are lots of ways to do paper washes, but I think that’s for another post..

And of course, you can always be bold and treat your colouring of your tangling like a colouring book – but this time you aren’t colouring in between someone else’s lines – they are all your own!
