Just received a FUUMUUI natural Kolinsky (or so they say) collapsible travel brush set. I already had two others, and am happy with them (go figure). The former ones seem to come in a leather case, this newer one comes in what is clearly PU "leather". I suppose margins also need to grow in China. As long as brush hair quality is good, the pouch is a minor issue, specially considering the price (which BTW is not that cheap compared to a WN Kolinsky brush set --save for the collapsible design).
Besides, I ordered a pad of 7 Artists A4, acid free, natural white, cold pressed watercolor paper made in Lithuania. Haven't tried it yet. Not even unwrapped it. I bought it to cut it to A5 and fold it to A6 to use it in refillable pocket notebooks. Tomorrow I plan on getting access to the precision paper cutter at work and will then unwrap it, cut it down to measure and get a first feel for its touch. I plan on bringing the notebook to London (I'm going there this weekend for a few days).
And finally, two Koh-i-Noor 5344, 5.6mm clutch pencils.
These will complete the pocket set I plan to carry on a pants pocket with charcoal, sanguine, sepia and white leads (I use Koh-i-Noor and Cretacolor 5.6mm leads) and a 5mm stump in a small leather pouch. Together with the A6 (A5 unfolded) notebook in another pocket, I can always have at hand a decent sketching set.
I still have to decide if I will carry a watercolor pencil/stick set, a 12-half pan watercolor tin box (and which one!), none or both. I guess it will depend on the weather forecast and my appetite for expending on Arts supply stores.
