Picnics require you to gather all of those bottles of mustard, ketchup, mayo, barbeque sauce, salsa, and relish to bring with you, so you fill up a bag loaded with a bunch of heavy bottles to take along. There is an easier way. Just use these 2 ounce containers to add everyone's favorite condiments and seal it with a snap-on lid. After the picnic just throw them away. Buy extras to keep on hand for those special occasions.
