Yupo

manufacturer Eckersley's
colour white coloured
texture SUPER smooth rough
surface delicate tough
staining soaks into paper floats on surface

notes:
Who placed yupo in the list of watercolour papers?
Lier! Lier! (ノД`)・
I wrote surface was "SUPER smooth", but it's really a SUPER ULTRA SPECIAL SLIPPERY SMOOTH X+.

Welp, you knew it is made of plastic... (´・ω・`)

Pencil glides like rollercoaster on this paper, and you can forever erase it and redraw and erase and redraw...

btw, out of all the pens I have,
Copic multiliner, no.
Pigma micron, no.
Zebra Sarasa, no.
Mitsubishi Jetstream, sort of, till you try to rub drafts off, and eraser just takes the ink along...

Winsor and Newton's drawing ink (951 Black Indian) was THE only ink that withstood yupo.

Now I see why Japan use yupo + pencil for their votes.

...and I said, you can't put WATERcolours on plastic!
