This cannister once held Russian Zvetouchny tea, or better known to some as Swee-Touch-Nee tea. The tea brand is approved during Pesach or Passover since it is Kosher and has been enjoyed by Jews worldwide for over 100 years – though predominately available in Russia and Europe. In fact, during the Holocaust, a tin tea canister helped a couple hide their jewelry from the Nazi’s. They had someone melt down their rings and hide it within the lip of the canister (the entire story is linked below).
