Measure the actual bottles and miniatures before buying a painting case. A box that fits dropper bottles laid flat may not fit them upright, and a rigid tool organiser can still damage a painted figure if it moves inside.

Pack three separate groups

Group Protection to plan
Paints and liquids Secure caps, upright fit where possible and secondary containment for a leak
Brushes and sharp tools Tip protection, guards and a compartment that prevents movement
Miniatures Support at appropriate contact points with space around fragile protrusions

For a flat organiser to compare, Plano’s 3700 storage range includes an open-compartment box . Check its actual internal dimensions against your layout. The 3700 family name does not mean every version has the same height or divider arrangement.

Test the layout without risking a finished model

Mark the internal dimensions on paper and arrange the bottles and tools within them. Allow room for padding and the lid. Use an unpainted model or a similarly sized object to test movement before entrusting a delicate painted piece to the case.

A waterproof label does not establish resistance to paint solvents, and a latching lid is not automatically childproof. Follow the storage instructions for every liquid. Keep blades guarded and keep hazardous materials away from children.

For a painting session away from home

Pack only the paints and tools needed for that session, plus an appropriate work-surface protector. Confirm the venue’s rules on liquids, spraying and cleanup. For air travel, check the carrier’s current liquid and hazardous-material rules for the specific products before packing.

Our small-parts and magnet storage guide covers the tiny loose pieces that should not migrate into the paint compartment. For choosing a minimal brush set, see brushes by painting task .
