Packing can be done in many ways  

Packing Example on packings: One by one in plastic bags. Or 12 and 12. Then in an inner box. Then again in an outer box perhaps 4 inner boxes in an outer box. But you do have other options. Study the market and bee creative. Also note that its important with packing instructions combined with suitable markings on the inner and outer boxes. Or else you will be looking for a needle in the haystack when you search for a given style in a given colour and size in your store. You are responsible to give the instruction for this.
