Current obsession: the Holbein Artist Colored Pencil

So my latest art supply obsession is the Holbein Artist Colored Pencil...*winks*

I splurged on a set of 24 on a recent trip to Japan and wished I had sprung for the 150 set because I LOVE them so much (they are pricey outside Japan *insert sad face*). They are the perfect in-between compared to the Prismacolor pencils (which are soft and very fragile) and the Faber Castell Polychromos (which are harder because they are oil-based). The colours are nicely pigmented, blend easily and are lightfast. They are sold in sets of 12, 24, 36, 50, 100 and 150 and also available individually. I got mine from Sekaido in Shinjuku, Tokyo.

Here is the first eye I drew with the Holbein Artist Colored Pencil.

Here is a quick 5 minute sketch I did with them.

Coloured pencil application takes time and a lot of layers (like 10 -15 to create a "painted" finish) but it's a less messy art supply to carry around when you are travelling. Here is the in-progress shot of the eye in the first picture which I started while waiting for my flight at the airport. 

It's weird that I'm obsessed with coloured pencils now as an adult. I wasn't when I was a child. I was busy making clothes for my Barbie. *LOL*

What about you? What is your current art supply obsession?
