Hi Galinia: Here (USA) Splenda comes both in individual packets and bulk. Sounds like maybe the "jar" one may be the bulk we use here. The large bag is 275 gms. and equavilant to 5 lbs of sugar. We cook with it all the time because hubby and I are both diabetics. Splenda has a web site. Perhaps you could send them an e-mail... have a wonderful day, Tootie
