Concurrent with her work on PADDI, Valerie also developed Nikini, an early version of a disposable sanitary towel system. Details about the exact development timeline are scarce, but it aimed to provide a more hygienic and convenient alternative to existing sanitary products.

Nikini was also commercialized, though its success was more modest compared to PADDI. Information on its market share and distribution is limited, but it represented an early contribution to the development of disposable sanitary products.
