13-Pocket A4 Expanding File

The Casio BK-13Pfolder-Black is a 13-pocket accordion file folder built for A4 and letter-size documents. It suits students, office workers and home users who need to sort bills, invoices, receipts and letters by subject. Colour-coded tabs with label inserts and a dedicated business-card slot keep categories distinct and contacts handy.

Build Integration — Desktop & Bag

The folder measures 12.99 by 9.7 inches and holds up to 360 sheets, so it replaces several single pockets on a shelf or in a drawer. Water-resistant plastic construction protects contents from spills while a reinforced elastic cord and bungee closure secure the bundle during transport. A built-in pen pocket adds a writing tool without extra bulk, letting the unit slide into a backpack or briefcase.

Sustained Load Behaviour

Under daily use the water-resistant material resists deformation and odour buildup, maintaining shape even when fully loaded. Reinforced gussets and the elastic cord closure keep pockets aligned and documents from slipping out during repeated opening and closing. The lightweight plastic shell stays rigid over time, so the organizer continues to protect papers without cracking or warping.

Questions about this item

How many sheets can the 13-pocket folder hold before the elastic cord closure becomes strained?

The folder accommodates up to 360 sheets across its 13 pockets before the elastic cord closure is fully extended.

Does the water-resistant plastic material trap heat or emit odour when the folder sits in a backpack all day?

The supplier states the material is water-resistant, odour-free and does not trap heat during extended daily carry.

What paper size must I already use for the 12.99×9.7 inch pockets to fit without trimming?

The pockets are sized for A4 and letter sheets, so you need documents in those formats to file them directly.
