The Natural U-Cup 380 ml is our U-base 13 oz thinwall — 11.5 g of PP food-grade, 95 mm narrow rim, designed for layered drinks where the base curve concentrates toppings (boba pearls, jelly cubes, fruit pieces) at the bottom for a cleaner ingredient read.

Best for
- Boba and bubble-tea operators — U-base settles tapioca pearls at the bottom in a tight cluster, photographs better than a flat-base spread.
- Layered milk-tea and signature drinks (gula aren, brown sugar lines) where the U-curve compresses the layered gradient against a narrower base.
- Fruit-tea and topping-heavy menus (lychee, longan, basil seed) where toppings stack visibly at the U-base instead of spreading across a flat floor.
Material rationale
The U-base profile changes the cup's centre of mass — 95 mm narrow rim with curved base is more thumb-stable in hand than a 114 mm flat cup at the same height. PP food-grade carries the cup at 11.5 g without buckling under typical cup-sealer film tension; the curved base actually adds rim rigidity by distributing sealer down-stroke load through the wall arc. Crystal clarity stays at ~88% light transmission so layered ingredients still read through the wall during service.
