Around $9 - $11 elsewhere in NZ.
The side of the box says '24x27cm'. Here's a better image of the product.
Our reusable produce bags are light weight (the ones sold in Woolworths only weigh 3 grams), strong and easy to see through and, you can fit up to 2kg of fruit and veg in them.
If they get dirty just throw them in the wash. That way you can use them again and again. So this small change in our shopping makes a big difference to the environment.
