MMF Industries Cash Transmittal Bags | 9W x 12H | Pack of 100 | Unique Alphanumeric Numbering | Self-Sealing Adhesive | Four Tamper Indicators | Folded Bottom | Deposit Plastic Bags

These envelopes are technically the same size as the last deposit envelopes I used (which were fine from a security standpoint) but their interior dimensions are just a bit larger and allow for business-sized checks to be inserted horizontally rather than vertically. I also like the clear envelopes which means we no longer wind up accidently cutting the larger checks, which happened with the other envelopes (which were opaque.) These work well to secure forms and information that is confidential: the receiver can be sure no one else has seen the info. Of course for that purpose I generally fold the papers for confidentiality and for ease of opening - a full sized sheet fits but I haven't sealed an envelope as I think opening it without damage to the contents could be a problem.

This is the second time we’ve ordered these and we have not been disappointed yet.

These bags aren't as opaque as older bags of this same brand. A good flashlight, will let you see some.of the contents.

The tamper proof seal is excellent. Once it's on, that's it, no sneaking it back open. Best part of this bag for me is how easy it is to use. I've used several other tamper proof bags before, this one is by far the easiest to get done right. Other bags have had a removable strip on the back or some such where you have to fold the sealant over which can make a bit of a mess if you don't line it up just right. That is not the case with this bag, the design is much easier to use. The sealant strip is aligned with the top portion on the back of the bag, you just remove the backing from the sealant side and push the two sides together. No chance for bags getting stuck to each other or other things from misaligned sealant strips or sealant strips folded over with sticky corners sticking out. Good value for the money and while the easier sealing is a small thing my clerks appreciate it.

We purchased these to use for our Little League Baseball organization concession stand. Before we purchased these bags, we were at a loss to get to the bank on time every week to get the night drop bags so that we had them on hand to empty the register after each days' games. Instead we just get out one of these bags, write our information on the front, include a deposit slip and the money and drop it off. The bank mails us our receipt and we do not have to go out of our way anymore.You will need to use a ballpoint pen to write on this BEFORE you put the contents in. Once it is sealed, that's it. It's sealed. And it seals much easier than the "older" style bags. You just pull the backing from the adhesive and it closes almost on its own.

We use these at our church for our deposit and they work very well.

We use these for church. Love them, bank has no problem with them, so much better than having to retrieve the reusable pouches from the bank. Stuff, seal, drop, done. I keep them on reorder. Also cheaper on Amazon that I can get locally at the office stores. Plus I got tired of going to the office store to find they were out of stock. Amazon Prime and reorder are awesome ways to keep the church supplies coming.

Easy to use, even for fumble fingers. The only complaint I have is the requirement for a regular ball-point pen - naturally that is not what I use, so of course anything I write on it smears. But I love that no one can see what is in there because it is not transparent, and I love the feeling of added security it gives me.

Fantastic Product as advertised and good material.
