two pocket heavy duty folders

Most listings specify US letter (8.5" x 11") compatibility; some also reference A4. (A few listings repeat the letter size in alternate notation such as 11" x 8.5".)

Edges are often sealed to resist tearing—some listings specify high-frequency ultrasonic sealing—while pockets may use notched designs that act as stress guards to protect seams from pulling or tearing.

Listed sheet capacities include 20, 25, 50 and 100 sheets. (One product description also claims up to 36 pages but its bullet list states 20.)

Communication folders commonly include two interior pockets sized for 8.5" x 11" papers, labeled left/right pockets for home and school use, clear front or back pockets for name tags, and tear- and water-resistant, easy‑to‑clean construction with seam protection features.
