Review on Pen Filament Refills Book Including by David Moreno

I am happy with the amount of yarn I got for the price. However, there are some major downsides: This PLA requires a higher temperature than others I've tried. The range says 170 to 210 but it only seems to work well at 200 - it cools incredibly quickly so you have very little time to manipulate the strands - the speed at which it cools means the tip of the thread (part of the tip of the pen) is usually hard which makes the first 1/8 inch or so unable to stick to another surface - I can't make as clean/smooth creations with this PLA as others. I would say don't use this for fine detail work, it's great for wireframe or other wider work.
