Engraving GuidelinesComplete product details can be viewed on our Tag product page here. The included tag personalizer form on the tag product page will guide you, as to how much you can fit per line / per side. You will see a preview of how your engraving text will look as you type. Tags can be personalized on both sides (EXCEPT for slide tags - front only). Each side can fit up to 4 lines of text, 14-characters max per line (including spaces). Character count includes text, punctuation and spaces. We highly recommend using 1-3 lines for best results & improved legibility.Once you have added the tag style(s) you want to your cart and are on the Shopping Cart page, you will see a 'Special Instructions' message box to type in your instructions for the text you want engraved on each ID tag you order. If we have any questions after you've made the purchase, we will contact you.The less text you use, the better (and larger) the lettering will look. The engraver auto-sizes the text based on the widest line of text and the # of rows of text it has to fit. Text is always automatically centered vertically & horizontally. Legibility is always guaranteed.Typeface & Special Characters — We offer one font. It is a clean & clear-looking uppercase style (see photos) to ensure optimal legibility. Emoji symbols and special characters (À,Ü,È,Ñ,Ø...) are not supported.All of our tags are removable and can be purchased separately except the slide tag. Note: Slide tags require a collar purchase from our shop because they are not removable or interchangeable. They are added during the making of the collar and cannot be removed due to the buckle blocking one's ability to slide the tag off.If purchasing a slide tag with a collar -- note that the slide tag will reduce the maximum adjustable length of the collar (because the length of the slide tag limits the extension). Your collar's minimum length will remain the same, but the maximum extended length will be shorter by approximately 1.5 inches. If this is a concern, please add a note in the 'Special Instructions' box indicating the neck size you need us to make sure we can accommodate when the slide tag is on the collar -- we will modify the collar during production accordingly.Please remember to leave engraving instructions for your tag(s) in the Special Instructions box on the Shopping Cart page. If ordering a slide tag(s), indicate which collar style goes with each slide tag.
