Thank you for viewing! This is a green and white smartphone case with a shoulder strap for the Galaxy A25 5G! It's a back cover type with a strap for diagonal carry, shoulder carry, neck carry, and a string, and it has card storage! The dimensions of the part that holds the smartphone (the black part) are approximately 17.8cm in length and 7.5cm in width. A coworker mistakenly purchased the wrong Galaxy case on Amazon, thinking they had ordered a different model. They didn't realize it until they opened the package and tried to put their phone in. They noticed it was the wrong size and unfortunately scratched the top of the case and made a small line, making it impossible to return. They asked me to list it on Mercari, so I'm selling it on their behalf! It's practically unused and there are no issues with using it! The string hasn't been opened at all! The smartphone case box was discarded when it arrived. Please understand the above, and I would like to sell it to someone who likes the smartphone case!
