Some objects deserve supplemental information, to be used together with the object. If the information is small, a marker or label is sufficient: one can write "Take with food" on a bottle of vitamins. But how would you attach instructions for a small device, like "Set the EMS value to 0.78 for foreheads" for an IR thermometer? Or "Mix (in order) 1 mL bleach with 175 mL water, then 1-2 mL of white vinegar to make first aid wound rinse. Store sealed without headspace, replace yearly." I don't want to ever need to redo that calculation--I want it stored on the bottle. (If you are curious about this, google hypochlorous acid wound rinse.) For rechargeable batteries: "Bought Jan 2020".
I'm looking for a solution that is not an eyesore--taping very large labels to these objects would not be ideal.
Edit: the one that's really annoying me is a palm sized programmable ozone generator that I'll use to help deodorize some old refrigerators, and for sundry purposes. What I need to remember are the settings: mode 1 is low power, mode 2 is low power but only run once, mode 3 is higher power for a short time then go to mode 1, mode 6 is delay then go to mode 3...
