Sponges come in all shapes and forms.

This small set contains 3 white rubber type sponges that are good for moving the wax colours around, especially on the hotplate or during hot air working onto card, canvas or board.

The orange sponge is textured and also far more absorbent. This is good for creation of textures, foliage for instance.

All the above can be cut into other forms or angles and even torn to give more random edges.
