Panda oil pastels transfer colour easily and have a paper wrapper to keep hands clean. They are vibrant and suitable for various techniques such as gouache, watercolour, and the "repelling technique" with Ecoline.
Yes! You can use them with gouache, watercolour, and Ecoline. A fun technique is to apply Talens Opaque Black over the pastels and scratch the paint once it has dried to reveal the colours underneath.
