Re: Question about SB containers.
the glad containers work fine for home use. They'll be fine if you keep your containers nice and upright.
But if you travel with them at all, or they tilt at all, use lock-n-lock. I put AW vanilla in a glad container (medium juicyness) and it started to leak through the seal. The glad containers use plastic on plastic and you just press them down. Lock-n-lock uses a rubber ring around the edge that locks in place.
Not saying one over the other, just saying each has it's pros and cons. The cons of lock-n-lock are price.
