Use Barton Blue 4. 6 Litre Small Parts Containers (10031) together with Barton Louvred Panels (sold separately) to store fiddly components and fittings in an organised, easy-to-use system. These trays are manufactured from robust polypropylene that can withstand high temperatures and most industrial solvents. But despite their durability, they're non-toxic and suitable for food storage. The semi-open design makes it easy to see the contents at a glance. Add your own label in the index card slot for quick identification.
