Not all of us put in the time and effort when buying a gift, where those who actually do, are the best of the lot. It shows you care and love this person enough to put that much energy behind something that sounds simple, yet isn't.
An engraved ring could be a great gift for making your hubby feel special. You should be very careful while selecting the words that you wanna engrave on the ring; something that would make your husband feel proud. You may also go for engraved cuff links or a leather wallet.
