the intention with the introduction of coin4 was to present a case completely different to any other case found in this, over-saturated, market by introducing features that no other one until now has offered.
first, the curved rear surface allows easier and safer grasping and use. then, instead of offering a second accessory to act as a stand, in the overall form, we integrated slots where coins can be inserted and transform the case to a stand.
phone users, everyday “have” to remember to carry with them so many things such as iphone, charger, earphones, keys etc. why should they have to remember to carry their phone’s stand?
this solution, also allows to offer 2 products in one, to make this case cheaper as not extra parts are needed for the stand function but also avoid creating over-complicated forms and functions.
and as for the coins, whatever kind of coins someone carries in his/her pockets, be them taiwanese dollars, u.s. dollars, euros, yens or coins from any other country, no worries, he/she will find one that will fit or lock in the slots.
