The lockdown gave me the opportunity to try the three Daiso Pens. The Daiso Platinum was a failure ink on the section.The nib wrote rather soft.
I took an emery board for manicure to the nib of the Daiso-Platinum Riviera, and now it writes a bit more to my taste so as to avoid getting thrown into the bin; it's "earned" itself a place on my fridge as what I use to write my shopping lists (in Platinum Carbon Black ink, so that it's completely waterproof in spite of getting damp with sweat or even when soaked in the kitchen sink).
The third one , the Daiso Hauser wites a thin line on almost any quality of paper;not very easy to uncap but has not shown any stress lines or cracks. I'm happy with the last two pens, good as an extra pens in case someone ask to borrow your pen.
I bought several more of the Daiso-Hauser pens, filled a couple of them with Noodler's Blue Ghost (after adding converters I took from Nemosine pens), and gave them to the young daughters of a family friend. Reportedly they're still mad keen to play with those pens, but at least they've stopped writing "secret messages" all over the walls. (I also gave them each a little UV flashlight, and a larger one to their mum expecting she'll want to see what mischief the girls would be up to, haha!)
Next time I see them, I'll give them a "better" fountain pen each — Platinum Prefounte in their choice of colour out of the five available, as I have a new one of each in my stash, and a choice of an Aurora Ipsilon, Lamy Studio, Pelikan M200 or Sailor Procolor Shikiori as a "starter" pen for their mum, since she expressed an interest in fountain pens last time we saw each other before all the COVID-19 nonsense.
