Marks Mixes are made in a water-soluble powder. Powders are more affordable to ship giving you more for your money. Powders are more stable then liquids with a longer shelf life. Marks Special Tea could not be made in powder & maintain its quality & integrity. All Marks Mixes have a 2-year shelf life. The powders will last much longer if stored correctly.
Please store all of Marks products in a cool stable environment 50 to 90 degrees with lids on when not in use. DO NOT leave in the HOT sun!
