However, according to Chinese medias, they are for the most part a Chinese company, with product design and product made in China mostly, which is associated with the same issues that the stereotypical entails.
For example, some of their products were direct knock offs of Muji/Uniqlo design but made with cheaper material and likely lesser quality to keep prices low. Some of their graphic design were knockoff of other artists with little to no design changes and repainted on their products. There is one news that reported Miniso had announced known European designers had jointed their design team but those people only found out about it when the media had contacted them. A lot of them had prior contacts with Miniso but never a full commitment with them since they always drop off the radar once contacts were made, but all of a sudden their names show as "in house" designers.
So, people shopping Miniso should know that they may be buying form a company that would not only hide their true origins, shamelessly knock off from others of their logo, product design, graphics but would seemingly lie about things they do and likely the product they sell too. This is just on the surface of what they do and had done too, imagine what short cuts they may be willing to take to the design and quality of their products, what materials they may use to keep the prices low and profit high ??
