Small Smell Proof Bag and Credit Card Holder w/Hidden Compartment - Minimalist Wallet for Men (4.5x4x1 inch) - Slim Low Profile Travel Container - Vegan (PU) Leather - Pocket Size

- Nice fit for the Arizer Argo which can be a bit smelly in your pocket without a cover. This bag reduces the smell and fits in the additional Argo tubes as well which is great but the tiny 1-2mm hole which is left after closing the zip unfortunately leaks a bit of smell, so it's not 100% smell proof but better than without any bag.- Outer material is ok and I hope the zip will last but time will tell

Excellent quality and completely smell proof.
