Review on Sakura Pigma 30063 Micron Assorted Colors Ink Pen Set - 01 Tip, 6CT Blister Card by Amanda Castillo

I originally bought a set of 6 colors (size 01) a few years ago to emphasize in my bible and they are great for that purpose - though they're still spooky, they never bleed through thin pages. However, I recently bought some black sheets of the same size (01) to use in my notebook. After only 5 weeks of moderate use (a few lines and a sentence or two a day) the pen is practically unusable as the tip has flattened out and pressed into the metal body. I have a photo comparing the broken pen to one of the unused ones in this pack. I'm not an artist so there might be a 'proper technique' you should use with them that I don't know about, but I don't press that hard when painting so I expected them to last longer . . Also the label on the lid identifying it as a black 01 is already completely worn out - I'll be throwing it away soon anyway, but if I were an artist with lots of colors and sizes I think it would annoy me. Compared to the later purchased Staedtler pigment liners (which feel more durable when writing and have the size pressed into the cap so it can't be rubbed off), these just feel cheap. Like I said, I think these cherry blossom microns are great for highlighting Bibles, but I wouldn't use them for anything else.
