Actually are waterproof
I got the 0.1 sized timelines and they are exactly what I wanted. The right size and they really work well on the page. They also don’t smudge and are permanent and waterproof too. I can outline my watercolour with them and then paint over them and they don’t bleed. Fab product.

Perfect daily driver pen for me
Writes great and leaves an even line after a month or so as long as you leave it capped. I like the new packaging, there's so much less waste.

Uni Pin Fineline pens
Nice pens and fine nib. I hadn't realised they aren't as quick drying as another make I use dries almost instantly. They are still good pens

Highly recommend.
I'm happy to recommend these. I do a lot of illustration work & these are great to work with. I prefer them to the copics & sakura pens & they're cheaper too without sacrificing any quality of line. They are warm & light weight, comfortable to hold for extended periods of time, the nibs are nice and flexible and I can vary the width of line significantly from the faintest scratch to a bold thick sweep to add flair & vitality to my drawings. U will have to experiment to find what suits you best personally but I really love drawing with these pens. A full 5 star.

Love the ink & the pen writes wonderfully. They are wider than I thought. It's my own fault for not researching them better. I will use them but not for my intended purpose of drawing.
