    Clogged Staedtler Mars Matic .04
  

*by J***N on Reviewed in the United States on 28 May 2024*

Shook this well and it still clogged up a brand new Staedtler Mars Matic 700 in the 04 size. Unsure if I want to try it in anything else and see if it's the ink or the pen.

    Utile

Molto utile per riempire le cartucce dei rapidograph, così da non doverle comprare nuove.

    Quality ink and bottle - tips on opening bottle.
  

*by J***D on Reviewed in the United Kingdom on 18 November 2020*

I used this to refill my Reform Refograph 0.35, a pen I have used for over 30 years. The ink runs smoothly and dries quickly, which is the most important fact. The bottle requires a little patience to open but I don't think this is because it is poor quality but because it is good quality. Here are my tips, which result in no spill or mess at all. Once you screw off the black cap and then lift off (not screw off) the clear plastic nozel cap you will find that the nozzle is solid down to the ink level. I found what works is to take a thin nail (which has a pointed end) - the bronze looking type you lightly tap in the wall to put up picture frames and just lightly tap it down into the nozzle. If you do this gently the nail will eventually pierce through to the ink effortlessly. Then you gently lift the nail out, wash the nail and put the clear nozel cap back on and screw back on the black cap. The nozel will now work perfectly and you will have a nice clean small hole into the bottle through the nozel, which will help avoid clogs. If you use a paper clip (which has a flat head), you will quickly find it difficult and then you will start applying too much pressure and then pop all the ink will spray out and you will be left with a mess and a screwed up nozzle. Hope this helps. Small bronze nail, gently tap tap in with hammer into the nozzle and then gently remove.
