What breastmilk storage milkbags do you recommend?

A few of my friends used Honeysuckle Breastmilk Storage bags and recommend this brand as they have not experienced any leaks using these bags. They also felt that the material used (BPA-free) seemed thicker and more durable than some others they've tried. These can be purchased from this website: http://poshbaby.sg/products/honeysuckle-breastmilk-storage-bags 50pcs, $19.90
