This is a exclusive hand cut vegetable tanned leather patch with an engraved phrase.
The patch is 3" in diameter and features pre-punched holes to allow for easy attachment.
Please note that the back patch leather will patina with age, meaning it will darken and soften with wear as intended. See this link for more info http://www.understatedleather.com/pages/care-guide
