Gaelic Themes makes those pins along with the matching Cap Badge and Clan Crest Belt Buckle.

I keep a supply of them in my shop and have adopted it as the Freedom Kilts Motto.

I have used the same for my personal motto for many years.

I'm down to three Belt Buckles but if anyone needs one, right now, an e-mail or PM can have one on it's way to you.

BTW, don't go looking for the design on the Gaelic Themes Website they don't list it. I know Rocky has a commercial account with them and can order them as can I.
