MMF Industries Seven-pin Security/Night Deposit Bag with 2 keys, 11 x 8-1/2 Inches, Royal Blue (2330881W08)

I'm very impressed with the quality and durability. Contrary to some negative reviews, this is not designed to prevent a break-in, but to prevent tempering. This way you'll know if the bag was opened.The zipper is heavy duty brass and will require a break-in. I've found that rubbing a white candle on both zipper halves and opening and closing the bag a couple dozen times will make the zipper work smoothly with no roughness. I've been doing this with my heavy duty winter jackets for years.

The zipper was really stiff when I first got it, but it has relaxed a bit and works great. This is a very well built security bag and looks like it will last a good long time. The locking mechanism is very sturdy and looks very reliable. If someone was really desperate to get inside the bag, they could cut it with a razor, I imagine, but short of that, this is a nice and secure way to store your small valuables.

For a tough and durable and very high security 7-pin tumbler lock mechanism I cannot recommend this locking cloth zippered security envelope highly enough! The product is built to last for years. The zipper is military grade and is also built to be both tough and to last in spite of rough conditions during use. The lock, being made of 7 pins, is seriously pick-resistant. As for theft, be sure to choose well the hiding place during its transportation, such as to a bank night depository. If used well and with a maximum of care, this envelope will not let you down. My conclusion is that this is a superior product.

The zipper is stiff which makes it hard to use. Rubbing graphite (from a pencil) makes the zipper slide better. The lock feels durable and does not have a problem.

This bag is rugged and high quality. The lock appears to be military grade! Intense. We use it for sharing documents between administration and HR without prying eyes. Works very well. Large enough for full size folders. Sent back a different bag for being too small (due to rounded corner) but this one is just right.

These bags are durable and provided me with the extra layer of of personal security with my small valuables that I was looking for when I travel and stay in hotel rooms. I was able to just zip up and lock my bags and take my key with me and I was covered. You can never be 100% protected, but it would take a very strong blade to cut the material and most petty criminals or thieves probably wouldn't bother. It makes my small valuables a little more secure than most other hotel guests and that alone makes it worth the price.

Works great good quality

There is little chance anyone will get it open by picking the lock or by the lock's failure to engage the zipper. It feels like it will last a long time. It could be cut open with a knife or scissors, but the intrusion would be obvious. I use it to secure habit-forming (legal) drugs. I switched to this because the patient was able to pick open the real estate key lockbox I used previously. She has not found a way to get into this bag.
