You've got architectural plans, site maps, or a 40-page training manual that keeps tearing at the fold line. Standard protectors flex too much for A3 and the paper shows through after two weeks.
These Marbig heavyweight A3 portrait protectors are built to take the weight of thick, large-format prints without warping or creasing. You slide the document in, the film holds it flat, and the portrait orientation matches how you actually lay out plans and charts on a desk.
A pack of 100 means you're not running to the shop mid-project because you're down to four sleeves. Keep one on the shelf, use them as you go.
