Most people assume a simple plastic sleeve is just a disposable afterthought, but the Dunwell L-type folders prove that archival quality actually matters for daily organization. These aren't your typical flimsy sheets that crack under pressure. The poly plastic is remarkably flexible and tear-resistant, even if you roll them up in a bag.
