Trade your phone for a brick — the good kind.

Before smartphones tracked your every scroll, devices like this held your whole life: contacts, schedule, notes, calendar. No notifications. No algorithm. No blue light at 1am. Just you and your thoughts.

This Casio SF-4000 is a great fit for anyone doing a digital detox, dumbphone switch, or minimalist-carry setup — use it as a standalone notebook/planner instead of pulling out your phone.

Features: telephone directory, memo function, calendar, schedule function, and calculator, plus a password-protected “secret” storage feature. It has 32K of memory (about 31,902 characters), a six-line LCD that can display any month from 1901–2099, and runs on three CR2032 batteries.

Condition: Tested & working, no cosmetic wear, brand new batteries

Included: device only

Note: sold as a vintage/collectible electronic; not a modern replacement for phone functions like texting or internet.
