I've enjoyed using the smaller, business card sized version of these palettes – they're great when something really portable and discreet is needed. I find the tiny square pans a bit impractical, though, which means the smaller palettes can't take more than 14 colours – fewer if you want a mixing pan for washes. So I'm looking forward to setting up this folio palette. I think it will work well with 15 colours: 12 in the rectangular pans, and 3 more commonly used colours in the larger square pans, while still having lots of mixing space. The size is still very convenient: roughly the size of a Field Notes or Moleskine pocket notebook when closed. I wish the Folio palette were a little cheaper for what it is but I recognise that these come from a small business in North America and with the exchange rate and the costs of shipping at present, this is still a fair price.
