Sifo's niche was early educational toys.
Sifo catalogs of the period emphasized the various properties of their toys that would entertain and educate children.
Final assembly and finishing of the toys took place at the St. Paul headquarters and factory located at 353 Rosabel Street (now Wall Street).
Sifo's best known products were the Timmy Time Clock Children's game and the Kinder City city play set.
The St. Paul factory was razed and is now a parking lot.
