Empty Watercolor Pan Plastic Paint Cup (Select Mini Sample, Quarter, Half or Full Pan Size)
Empty plastic pan tray for filling with watercolor tube paint. Sold individually, per piece. Select a pan size option from the drop down menu. No writing or logos, blank on all sides.
Could be used with glue, double sided tape or magnets in your watercolor travel palette case or DIY custom containers like Altoid mint candy tins (great for pocket size urban sketching travel palettes). See ruler in photo for size reference.
PAN SIZE OPTIONS:
Mini Sample Size (roughly equivalent to 1/6th pan) a 0.5ml tray measuring about 12mm x 12mm and 6mm deep. Ideal for super tiny palettes or an alternative to dot cards for handmade paint makers. About a third of a standard half pan, or a sixth of a full pan size. Could be overfilled to about 0.75ml. (For reference, half pans are the most common size tray seen in watercolor sets and those are typically 1.5ml).
Quarter pan size with curved edges. Outer edges measure 15mm x 19mm and 5mm deep (half the depth of a standard half pan). This option fills the same footprint space / container slot as a half pan (it's just more shallow/less tall). Ideal for selling more affordable options of expensive pigments that will still fit well into most travel palettes alongside half pans. The fill estimate is 0.75ml underfilled or 1ml full.
Half pan size measures 15mm x 19mm and 10mm deep. This is the size most commonly available in watercolor pan sets. It has a 1.5ml capacity (up to 1.75 - 2ml overfilled).
Full size pan measures 18mm x 28mm and 10mm deep with a 3ml underfill to 3.5ml overfill capacity.
Q&A Please note that pan sizes and wall thickness vary by brands. I can only recommend these pans for those building their own custom palette from scratch, or making handmade watercolors - not to specifically fit into a certain pre-made container. For instance Winsor and Newton custom make smaller half pan sizes, so their containers may require special pans. ML fill lines: Most standard "full" size pans are 3ml, but handmade sellers often overflow pans to fill above the top line ("pillow top"). Companies like White Nights offer 2.5ml cups and other brands go up to 3.5ml - but are rarely filled to the brim. Kuretake Gansai pans are extra large, a Japanese size for large brushes, that are much larger but more shallow than the "full size" pans shown here (gansai trays rarely even half-filled with paint). Sorry, I have not found gansai xl empty pans available for sale anywhere. While the "fill" line is technically the top edge, it's considered variable. Some companies overflow their pans, while others fill just below the top of the pan, some even dispense a set amount of pigment and if it shrinks later you get a sunken-in shriveled paint cake. If exact ml is a concern, I recommend a pipette or medical blunt syringe for determining precise amounts.
