Mangosteen.

Mangosteen is delicious, no doubt about it. You cut along the circumference of the fruit with a sharp knife, twist it so that the halves come apart and then lift out the sweet, white flesh.
I am still on my quest in finding supplies, but I did find this sketch book with very thin paper and a 16 color box of oil pastels. All in the children's drawing department of Carrefour. Although the drawing doesn't quite merit being posted, I did enjoy using the oil pastels (first time) and they blended really nicely when working from dark to light colors. They will work better on a slightly more toothy paper.
