Paper Quality: Typically features smooth, bright white paper (often 50–60 GSM) that prevents ink from bleeding through.
Variety of Rulings: Available in Bangla (single line), English (four-line), and Math (squared/grid) margins.
Binding Types: Comes in various binding styles, including pin binding (most common for school), sewing, and spiral binding.
Durability: The covers are made of heavy cardstock with vibrant, high-definition printing (like the sports and landmark themes seen in your image) to protect the pages from daily wear.
