Mesh bags in 3 different sizes - take them with you to the grocery store to contain your fruits and vegetables and leave the plastic one use bags behind. Extremely lightweight so you won't pay more for produce that's weighed at check-out.
Available with a tie-top or without. Tie-tops do add weight when using for produce in grocery stores that do not weigh the bag on arrival.
As packages of 3, one Small, one Medium, One Large. Keep them with your tote bags and automatically replace all one use plastic bags when you do groceries.
