The AmazonBasics Universal Case is exactly as what was posted. A small, compact, padded pocket for most small appliances (unfortunately my Navigerät did not fit in, it lacked about 1-2 cm). The design of the bag is quilted with internal padding, so that the equipment inside is not damaged in a case. The smaller cases are meant here and not the deliberate frustration throw against the wall, should be clear. Also, the bag serve as a splash to water, but also here is on individual drops conclusion.
The string is to be opened and closed by the push button and quickly on the back of the bag is a carabiner, which allows you to attach the bag what ever you want. A practical bag whose price I however find a little high. From me - as my Navi did not fit into his pocket and because of the somewhat high price - 4 stars.
