russell+hazel Acrylic Mini Hole Punch
A super-handy pocketable hole punch! Folds up to drop neatly into a pocket or pencil case, but unfolds to punch two holes in up to five sheets of paper. Usually, you have to choose between carrying a big heavy hole punch, or a more portable one that only does one hole at a time, making it too much of a pain to actually use. Midori have managed to get the best of both - tiny, but still punches two holes at once, and even catches the waste. Folds down to 67mm x 28mm x 22.5mm.
