I'm on board with those advocating the sleeve and top loader solution. Better protection, less sliding around. Throwing it in a team bag also helps. But imo, the best solution is always to have it graded in a BGS slab. Best protection bar none - most durable holder, the inner sleeve, etc. Somebody should create a holder that can securely hold a card in a penny sleeve, which protects the corners, etc. Don't know why this hasn't been made as it would better protect people's cards, and provide an alternative to those who don't want to going the grading route. Although one-touches are nice to look at, they share the same issues as graded holders made from PSA or BCCG - flimsy and cards always tend to move around in their holders.
