Thank you for your feedback, marilyn_k. We're glad these sheet protectors are working for your needs. As a lightweight, economical top-loading sheet protector, this Foska 0.035mm option is designed for everyday document organization rather than heavy-duty use, which is why it feels thinner or more flimsy than some premium alternatives. If you need extra durability, we'd suggest trying a heavier-gauge option like our QuickFit Top Load Sheet Protectors, which offer thicker, more rigid sheets. We appreciate you sharing your experience and hope these continue to serve you well for your filing needs!
