Off-brand is a term that refers to products that are not produced by popular or well-known brands. When describing these types of products, there are several synonyms that can be used. For example, the term "generic" is often used to describe off-brand items, as they are typically sold without a brand name and are much cheaper than their branded counterparts. Another synonym to consider is "store brand," which refers to products that are sold exclusively by a particular retailer. Other synonyms for off-brand include "unbranded," "private label," and "house brand." While these terms all describe products that are not branded by a well-known company, the connotation of each term may differ slightly depending on the context.
