### ⭐⭐⭐⭐⭐ Really great quality plastic bag, very strong seal
*by J***E on November 27, 2025*

Really great value for the money. Fits an average size shirt very well, I'd say like a men's size large dress shirt or smaller. Doesn't fit thicker things like sweaters or hoodies nicely . The plastic is very thick and very good quality. The seal holds very well.
