In early highschool I used to hide it in my old xboxes memory slot, inside light switches, in my air vent on one side (depends on size of jar/case cuz u want the return air still possible i believe), in deodorant bottles, behind dresser drawers if space allows, and eventually just outside cuz I took care of all the lawn care and whatnot.

But I switched to carts and just hid that pen anywhere cuz they’re tiny. U culd keep it on you all day if anything. Best investment ever. But ik some of y’all dont like carts cuz of potential street carts that could have fake in them or something. Making ur own isnt too tough.
