Their listed prices are separated by $22.75, so the right pick depends on what you mail most often.

Where each envelope wins
The QuickBooks double-window pack is the focused choice for a business or home office that regularly mails printed checks. Its stated fit for QuickBooks Laser checks and computer business checks makes it the more direct match when the check layout drives the mailing setup. The larger box also suits a routine where envelopes are used continuously rather than occasionally.
The 120-count #10 pack is the better fit for ordinary letters, notices, and other correspondence that use a no-window format. It is aimed at business correspondence, and its security pattern inside and privacy-protection features align with mail that is placed inside a conventional envelope rather than displayed through windows.
Product notes
500 Self Seal QuickBooks Double Window Security Check Envelopes - For Business
This Prime Business Checks option is for mail that begins with computer-generated checks. The double-window design is intended to display essential information from the enclosed check while keeping sensitive details from being exposed, and the description specifically names QuickBooks Laser checks and computer business checks. Choose it when that check-envelope setup is part of your ongoing workflow, especially if a 500-envelope supply fits the volume you expect to handle. Its concrete limitation is specialization: this is a double-window security check envelope, so it is a narrower match for mail that calls for a standard no-window correspondence format. The self-seal closure keeps the closing style straightforward for repeated outgoing mail.
Envelopes Letter Size, 120 Count Business Envelopes #10, Self-Seal Security \| #1
This choice centers on #10 business correspondence in a no-window layout. Its 120-envelope count can make sense for a smaller correspondence run, and the listed self-seal closure avoids a separate moistening step. Choose it for letters and other business mail where you want the enclosed document, rather than the envelope windows, to determine how addressing is handled. The security pattern inside and privacy-protection feature are relevant to correspondence placed fully inside the envelope. The limitation is capacity: the box contains 120 envelopes compared with the other option's 500, making it less suited to a routine that consumes envelopes in larger recurring batches.
Final choice by use case
Choose the QuickBooks Double-Window Check Envelopes for recurring computer-check mail and a larger on-hand quantity. Choose the #10 Business Envelopes for no-window business correspondence in a 120-count box. With a $22.75 listed-price spread, document format and expected mailing volume are the clearest decision points.
