This didn't warrant a new thread, but this is as good a place to post as I can find. I just hit the year mark with my train belt which makes my large bifold a year & a couple months so I figured it was time to oil 'em. I used mink oil & realized I shoulda done it shortly after I got 'em. I know Saddleback suggests waiting a year, but the mink oil really softens up the belt to just comfortable, if that makes sense. As far as the wallet goes, I should've oiled it as soon as I got it. My wallet's pretty thick with cards & such & the mink oil really made it "sit on" tender.
