SABRE is made by Security Equipment Corporation in Fenton, Missouri, which has been making pepper spray since 1975. The company states that every SABRE formula is made and lab tested in the USA, and the Amazon listing says "Made in USA" right in the title.
The top review on the listing is from a buyer who used it when their roommate, much bigger than them, attacked them. Two quick sprays stopped him, and the residue in the air was strong enough that the police couldn't stay in the house for long.
