change the product as the market is already completely saturated, and isn't it the idea of the mini company to develop new products?
what is new about your idea?
put a nice bright color inside. it has to be water-resistant and firm enough to be part of your keys.
engraving can be an option to offer customized usb sticks.
you have many competitors. make sure that the stick has a good design to distinguish it from others. moreover, you could offer personalized sticks. for example, with a name on it. or, for example, with "my photos," "my music," "university," etc.
great idea !!
different sizes and more designs
how do you want to produce that by yourself?
micro usb
no offense guys, but you should try to think of something original that hasn't been done before. in the ad campaign, i would suggest showing how robust the stick is because if you carry it on your keychain, it has to withstand a lot of pressure over time. the usb port must not bend or anything under any circumstances; that's pretty important (at least to me).
