MAILMEDIA B4 hnedá nepriehľadná poštová taška 130 g/m² samolepiaca (balenie 25 ks) 51603

This B4 mailing bag from MAILMEDIA stands out with its 130 g/m² paper weight—heavier than many standard envelopes, giving it extra durability for shipping documents and small goods. The brown opaque paper keeps contents private, and the self-adhesive flap ensures a quick, secure closure without extra tape.
