Packing fragile items can be difficult, as they require extra care and attentiveness. There are special boxes made specifically for glassware that you can purchase, but you can still pack items safely without specialized boxes.
Layer the bottom of boxes with cushioning of some sort in order to protect glassware from impacts. If glass items are heavy and thick, wrap them carefully and place them on the bottom of the box – lighter glassware can be stored on top to avoid breaking the thinner glass.
