Blue keychain with security features from SECOM. - Brand: SECOM - Color: Blue - Type: Keychain - Features: Security Thank you for viewing. I have kept this carefully after purchase. It is clean, but there may be oversights. There may be age-related changes in functionality, as well as scratches, scrapes, and chips. I do not know how to use it, so I am selling it as a junk item, as there may be malfunctions given that it is a precision instrument. Please be sure to check the profile section before purchasing. Please purchase only if you agree to the above and understand personal sales on a flea market app.
