Best. Item. Ever! All words you could engrave on both the front and back of this tiny dog tag necklace! The sterling silver charm measures just 7mm wide and 14mm tall (including the jump ring fastener). It hangs from a diamond cut curb chain which will sit close to the skin and can be ordered in a full range of lengths, from 14 to 32 inches. This gives options for both children and adults. The chain is secured using a spring ring clasp.
