Brand new, unopened. Quoting from the official website: This is an empty bottle with a TARPtoTARP original design, specifically for "ECO KITCHEN CLEANER". We received feedback that it's difficult to tell whose bottle is whose when multiple people are using them at a campsite, so we've created a space to write your name on the bottom of the bottle. This product is sold as an empty bottle, so please dilute the dedicated refill before use.
