How should I put it? The brand you are talking about is probably a marginal product of Oppein cabinets. The oppubin you mentioned is different from the real Oppein trademark, but similar. Also, Oppein is a registered trademark with an r logo. The imitations of big brands are usually TM, using company names instead of trademarks to confuse consumers and deceive consumers. When purchasing, you must be vigilant and look for registered trademarks to avoid paying brand-name prices and regretting buying counterfeit goods.
