Happy Birthday PRANK (but not really) Gift card Case

Its a prank gift card case that at first glance looks likt it has LOADS of crews.... 
it uses TWENTY 3x4mm screws and 16 6x2mm Magnets Why so many? to hold it strong and help keep the whole “it's screwed on” illusion

to open it just slide it sideways, you CAN'T slide it upwards.. again… to keep with the illusion…
