Custom engraved lock on day collar; affixed to best quality, shiny, 316L black stainless steel Shiny curb chain, with shiny ionized, gunmetal black SMALL heart padlock and TWO keys -- on a key ring. Engraving is your choice of one or both sides. Read the engraving instructions located in the PHOTOS in this listing, please.
Padlock size: about 7/8" (22mm) at widest point.
Padlock is NOT waterproof, because you can't dry the inner workings.
♥ Measure -- DO NOT GUESS ♥
See my PHOTO for "How to Measure" -- The option asks for total LENGTH of chain—•not• the neck measurement.
♥️ Day collars are NOT play collars. NOT for tugging; symbolic wear only.
♥ SAFETY NOTE: Wearer should have at least one of the two keys in his/her possession at all times -- or a pair of tin snips, in case of emergency. ;) The padlock is the clasp! CHOOSE length for chain.
