Ball point liquid motion pen with liquid filled body. Tip the pen upside down or from side-to-side and the colourful blobs inside will form bubbles and slowly gloop around in a hypnotic fashion. Twist the end of the pen and it exposes the nib, allowing you to write as the blobs float around inside the pen body. Available in three different colours.
