Practical details: WATER: The capacity of the integrated water bottle is 30ml (think: shot glass or small medicine glass). The end cap/water tank, if filled to the brim, holds 20ml. Obviously you won't fill it with the brim when painting, so you could fill the tank two to three times from the water bottle during a session. The bottle can be filled from a very slow running tap or with a small funnel (the kind produced for filling hip flasks) or a large pipette/syringe. Tipping out the water again is a bit slow – the mouth of the bottle is partly blocked by the interior of the palette and so the water doesn't flow freely. It's wise to leave the bottle open for a bit to really dry out between sessions if you're not using it frequently. PANS: The rails for the palette portion will accommodate three rows of standard half pans (Schmincke, for example, and most empty half pans you can buy). If you use the smaller Winsor & Newton half pans then you could fit five of these in each of the outer rows, but you'd need to find another strategy for holding everything firmly in place, as the anchor bars then won't fit. (The same applies if you try to place whole pans in the outer rows.) The central row will hold only four half pans, regardless of what brand you use. Those with access to a 3D printer might be able to increase the capacity with some custom pans, but in normal use this palette will hold 12–14 half pans. Review: This is one of the most compact options for carrying 12 half pans in the field and it's beautifully made – a true bijoux ("jewel") box. I've had mine for a few years now and almost never use the water bottle section (it's easier to carry water in a 30ml or 60ml Nalgene bottle or just use water from a drinking bottle) but the end cap/water tank is a very useful feature. And if you paint with a waterbrush then the tank is a great place to put a sponge and have it secure at the side of the palette. The lid/mixing area opens past horizontal, so I recommend attaching a magnet bar (the kind used to hold name badges in place) to the hinge side of the box, to stop the lid opening too far. The alternative is to use your fingers (handheld) or put something underneath it (table top). This mixing area will stain, but the enamel cleans up easily with a white plastic eraser once dry. Because of the limited mixing area – just two wells – it's important to be strategic about your colour choices and perhaps prepare pans with convenience mixes for colour combinations you use a lot. This is the main thing I miss from larger palette tins: that inner flap that opens out to provide additional mixing space. But if you want something really compact that's still able to hold standard half pans (so not the Art Toolkit credit card palettes), and with capacity for more than six colours (so not the only slightly smaller Portable Painter Micro), and if you can deal with having only two mixing wells, then this is a great choice.
