Semi-fungible token ("SFT") takes the features of Non-fungible Token ("NFT") and Fungible Token ("FT") into it.
SFT is best used for a generic product type, each product with unique features. The unique features of a product are tokenized as NFT while the generic product type (i.e. replica) of the said products is tokenized as FT.
For example, in online games, a hat is a generic product type (i.e. FT component), and the various unique features to a hat is the NFT component.
