Excellent product. I bought an extra pack for my sister in law to try out and her dog walker was very complimentary too. Sturdy, waterproof and unscented so doesn’t leave my pocket smelling like perfume. Will definitely buy again.

In addition to preventing single-use plastics from going to landfill, we’re committed to reducing our carbon footprint throughout our supply chain. Plus, for every order placed, we plant one tree to support global reforestation efforts.
