Simple Brown kraft paper envelopes. Not sure exactly how many pages they hold but I was able to slip in a writing tablet no problem. Seal is permanent- no additional tape needed.
We at M.A. Miller use these 9x12 envelopes all year round. For our regular bookeeping clients we use these to hand them their completed P&L statements. During payroll we will use to include their payroll reports and during tax season we use to mail out to clients and hand out completed tax returns. We prefer this style because we found out that we save money by using these envelopes because envelopes with clasps are processed individually at the post office and because of that it costs more money. Having all finished work in an envelope is best for the reason that all papers stay in place and clients wont have papers sliding here and there.
Hello we use these envelopes everyday with handing P&L to clients as well as once we have completed tax returns we will use to hand out our client's copy. These envelopes are very sturdy less expensive and you don't get charged extra at the post office because it does not have the clasp. Strongly recommend if you mail info in envelopes to clients make sure to use this kind. You will save money. So in your next order make sure to include a box of the Brown Catalog envelopes and you too will notice the savings.
