These are things you need to evaluate when choosing a jar size. Get a can that will blend with your home’s theme color. If you are in a modern kitchen, sleek stainless steel jars work best.

If you need cans that complement a country theme, go for old-fashioned ceramic cans with canister knobs. Clear glass jars are suitable for any home as you can easily customize them with ribbons or leave them plain.
