Range planning
What gets made and what gets droppedDecides which sizes a collection needs and, harder, which ones it does not. Most of the argument here is about the gap between two sizes: a bin that is one inch narrower than the one above it splits the range without helping anybody choose. This role also kills sizes that sell adequately but confuse the shelf.
Dimensional design
The inches that decide whether a bin fitsWorks backwards from cabinet and appliance interiors rather than forwards from a nice-looking shape. Standard fridge shelf depths, the clear width inside a 24-inch base cabinet, the height under a bathroom sink around the trap: these numbers set the outside of the product, and the styling happens inside what is left.
Materials and moulds
Which plastic, which wall thickness, which finishChooses resin and wall section for each part, and signs off the tooling that will make a hundred thousand identical copies of whatever is agreed. Handles are the recurring fight: a handle cut too generously weakens the rim, and a handle cut too tightly is unusable with wet hands.
Quality
What is checked before a batch shipsRuns the checks that catch the failures customers actually report: short counts in multipacks, handles that flex more than the sample, lids that seat on one corner. Measures rather than looks, because a two-millimetre drift is invisible to the eye and fatal to a stacking pair.
Photography and copy
What the product looks like before it arrivesShoots on white, shows the thing at the size it really is next to objects people own, and writes the description. The internal rule is that every sentence has to survive the product arriving: if a phrase would make somebody opening the box feel misled, it does not ship.
This catalogue
Prices, availability and what this site saysKeeps the figures on these pages current, marks products that have no current price rather than hiding them, and maintains the sources on the pages that touch food, damp and child safety. When a claim cannot be checked, this role takes it out.
