The Etchr Mini portable porcelain palette is 0.9cm high and 7.5cm wide. Each of the 37 wells is 6mm deep to take as much paint as needed. The Etchr Mini Palette comes with one colour wheel, one mixer and one 200 GSM cold press colour chart to fill it up with chosen colour. All of this comes inside a small plated steel tin, separated by three cotton pads for a bit of optional padding between the palettes and watercolour chart.
