When packing your lunch you will sometimes need to have an IcePack. But most icepacks are bulky, making it hard to fit them in. So that's why I made the Mini Ice Pack For Lunchboxes.

The sphere is only 3x3x3 cm making it small and convenient. for lunchboxes and containers. To set up, fill the sphere almost to the top (leaving room for the ice to expand,) then put the cap on and place it in the freezer ready for your next lunch.
