What is white coffee, and why did the Manner cup draw complaints?
White coffee is coffee made from beans that are lightly roasted or, in some markets, brewed without the dark roasting stage, so the drink keeps a pale color and a milder, grain-like flavor. The Manner silver stainless steel straw cup complaints are a separate matter: buyers reported the lid's silver coating peeling after rinsing in water.
The silver version of Manner's stainless steel straw cup launched on September 2 with 60,000 units, available through delivery by buying two iced coffees. Within 12 hours, buyers reported peeling on the lid, which packaging lists as PP plastic with a metallic finish. The episode does not change whether white coffee has more caffeine.
Manner has long been known for its "bring your own cup and get 5 yuan off" policy and for frequently giving away stylish cups. The stainless steel straw cup launched last November sparked controversy because it could only be obtained by purchasing a 75-yuan set meal. After more than half a year, on the last day of August, the official announcement added a new silver version, which officially launched on September 2, with inventory increased to 60,000 units and relaxed to be available through delivery channels by purchasing two iced coffees. The high aesthetics and low threshold had cup enthusiasts rubbing their hands in anticipation, with many waiting early on the mini-program or delivery platforms for price changes, placing orders on time, and waiting for delivery. However, less than 12 hours after the campaign launched, complaints began appearing on social platforms: after rinsing the new cup with clean water, the outer side of the lid showed paint peeling, as if the silver coating had been scratched, instantly blemishing the originally eye-catching new cup. Some netizens checked the packaging box information and found that the cup body and straw are made of metal, while the lid is PP polypropylene plastic with an outer silver coating, which easily peels when exposed to water or lightly scratched.

Today's young people's obsession with cups has almost become ingrained in their bones. As soon as they see a cup with outstanding design, they fall in love at first sight, and if it also comes with a "free giveaway" tag, being won over takes just a moment.
In the cup giveaway arena, Manner, which has always adhered to "bring your own cup and get 5 yuan off," is truly a model worker, and the styles it brings out each time always precisely hit the aesthetic of the beauty-conscious.
Last November, Manner launched a stainless steel straw cup in three color schemes, which quickly attracted the attention of appearance-focused fans with its impressive look, and the cup's design and bundled set meal were hotly discussed on social platforms. However, the official acquisition method at the time required purchasing a designated 75-yuan set meal in-store, which included three large hot drinks. Various complaints not only dampened everyone's impulse to order that day but also brought considerable criticism to the brand's topic of exceeding a thousand stores.
After more than half a year, on the last day of last month, Manner suddenly announced that last year's stainless steel straw cup would add a new silver style, launching on September 2, which was yesterday. Unlike last year's white, green, and blue colors, the silver metal shell gives the entire coffee cup a cooler vibe. As for the acquisition method, there was no suspense—it was still the old rule of "buy a set meal and get it free."
But compared to last year, the official conditions for getting the cup this time were clearly much "looser." First, the cup inventory was directly increased to 60,000 units; second, the activity rules were changed to support ordering through delivery channels, and the set meal with the giveaway changed from the original three large hot drinks to two iced coffees. Sure enough, the high-aesthetic new cup plus a simpler threshold directly maxed out the expectations of a group of cup collectors, who were just waiting for Manner to start selling.
Drawing on past experience with grabbing merchandise, many clever office workers have quietly learned to place orders in advance. They no longer get up early or stay up late to wait at stores, but instead wait quietly on the mini-program or delivery platform for the official set meal price to change, then pick a suitable delivery time and immediately submit the reservation. This way, they can sleep well and still receive their desired cup on time the next day—killing two birds with one stone.
As office workers spread the word, more and more cup enthusiasts successfully got Manner's new cup, and posts and new photos praising the cup's high aesthetics kept popping up under the brand's topic, attracting many passersby who don't usually drink coffee, pushing the campaign's popularity higher and higher.
However, less than 12 hours after the campaign launched, Manner's stainless steel straw cup began receiving complaints due to paint peeling.

Consumers posted successively that the cup was intact when it first arrived, and they couldn't help but praise it profusely, but unexpectedly, after a simple rinse with clean water, the outer side of the lid showed varying degrees of paint peeling, as if the silver coating had been scratched. A brand-new cup instantly bore conspicuous "flaws."
Everyone thought such a situation might be isolated, but when they clicked on Manner's related topic, it turned out to be full of "victims" just like themselves. In just a few short hours from unboxing to use, the new cup's aesthetics had been compromised due to the lid's paint peeling.
In response, some netizens photographed the packaging box information of this stainless steel straw cup, which showed that only the cup body and straw are made of metal, while the lid is PP polypropylene, i.e., common plastic material, with an outer silver coating, so whether exposed to water or lightly scratched, it easily leads to the "paint peeling" problem.
