Heavy-duty expanding wallet is extra wide to allow top-tab file folders to fit neatly inside without bulging outside gussets. Heavyweight, 24 point, soil-resistant cover protects important documents during transit. Standard file folders fit inside with no interference on sides. Tyvek-reinforced protective flap with elastic-cord closure is extra long to assure adequate coverage even when the wallet is full. Rip-proof Tyvek reinforcements across inside flap offer added strength. Fully lined, Tyvek gussets with an added rollover feature protect against tearing. 7" expansion holds up to 1,600 letter-size sheets.
