Flat Cosmetic Pouch

One zip, two panels and no base at all: a flat cosmetic pouch is the simplest shape in the group. Sizes cluster around 7 to 9 inches long and 4 to 6 inches tall, holding 1 to 2 liters, and a shallow gusset of an inch or two is as much structure as any of them carry. Contents give the pouch its shape, which is exactly why it slips into a bag that has already been filled.

Absence of structure is the design, so the lining and the zip carry the whole of the quality. A wipeable coated interior matters more here than in a bag that lives in a bathroom, because this one rides inside a handbag next to a phone and a notebook. Watch the zip ends, since a flat pouch gets opened by pulling against its corners and cheap tape frays there first. A wrist strap or a small D ring turns it into something you can carry down a hall on its own.

Where a dopp kit stands open on a counter, this collapses and shows you nothing. It works by category instead of by view: one pouch for makeup, one for medication, one for cables. Brush rolls do a job it cannot, because brushes packed loose in a pouch bend and pick up powder from everything around them. Clear travel bags share the footprint and swap privacy for speed at security. Inside a hanging bag, a pouch like this is what fills the largest panel.

Daily makeup, a handbag touch up kit, and any traveler who prefers three small pouches to one large bag should own several. Size one by standing your tallest item inside, since a mascara at 5 inches and a foundation bottle at 6 will settle the height for you. Turn a candidate inside out and check that the seams are bound rather than raw, as a raw seam sheds threads into loose powder. Wipe it out monthly, because pigment left in an untouched lining sets and never lifts.
