To work with the books of Leng, you need an answer board. We make the answer board from recycled irrigation tubes (100% recycled plastic). It’s an intense process of cleaning, cutting, shredding, melting and pressing but this way we are able to clean up a product that is doing a lot of good for Cambodian agriculture but is also a bulky source of plastic trash. The answer board comes in a bag made of old jeans.

To play the game you also need 12 colored game pieces. They are made of simple bottle caps. These game pieces are obviously included.

With Leng you can practice at home what you have learned in school.
