Makeup drawer dividers are most useful when they turn a cluttered drawer into a layout you can actually maintain. Before choosing a set, measure the internal drawer space and work out which products need the easiest access.
Products and current UK buying options

Product information is researched rather than based on hands on testing. For a named product, confirm the selected model and variation; category links show a changing selection of results.
Measure the drawer you own
Take the usable width, depth and height inside the drawer, not the furniture's outside measurements. Allow for runners, hinges and any internal lip. Then measure the palettes, brushes and bottles that will sit inside it.
Height is easy to overlook. A tray that fits the drawer footprint can still prevent it closing if a tall lipstick or compact sits above the rim.
Fixed trays or adjustable dividers?
Fixed organiser trays make a predictable grid and can usually be removed for cleaning. Their weakness is wasted space when your products are awkwardly shaped. Adjustable dividers can give more flexibility, but the ends need to stay secure when the drawer opens and closes.
If your collection changes often, a combination of a few small removable trays may be easier to rearrange than one elaborate fitted system.
Build the layout around daily habits
Put everyday products towards the front. Store occasional palettes and spare items further back, where they will not obstruct the things you reach for each morning. Shallow compartments make small products easier to see, while deeper sections can accommodate larger bottles where the drawer allows.
Do not create so many compartments that removing an item becomes fiddly. The point is faster access and easier cleaning, not a perfectly packed photograph.
Materials and cleaning
Clear plastic trays make contents visible, but look at edge finish and whether the base may slide or scratch the drawer. Smooth washable surfaces are useful around powders, creams and makeup residue. Check that the organiser can be lifted out without emptying everything.
