Importing phone case samples

Hi I have found a lot of phone cases online and I have a question regarding importing samples.

I was wondering that if phone case has a size for iPhone 4/5/6/7 for me to import, should I import one of each?

Hi William,

It's not a market I know at all personally, but if it were me importing then I would only be taking on the latest cases to limit my risk. My assumption would be that older phones already had cases or most did anyway by this point. Drop-shipping older cases might be an option, but I'm not sure tying up cashflow in stock would be a smart move.

Cheers
