Ihave just taken a 30 pocket plasic page and cut off the strip where the 3-rind is. No slippage of chips. The pages slip in nicely, but What I don't know what will happen when you deliver the package to the post office. Sealed Up. Ist, i'll sail throw. 2nd, a woman clerk will ask what in hell do you have in here that weight so much? 3rd, You'll get a Old poor speaking english person that will call his/her supervisor and give you the 3rd degree, and you won't understand what their saying, Or I'll just go through. Good luck Happy Chippin.
