Straight Kettle Special Kettle Long Back Bag Banana Color Matching

In the past, I always had to trouble everyone to measure the length of the water bottle strap they wanted, thank you for not feeling troublesome (hands are better than love)~ This time I made a public version of the strap length, Let everyone adjust the strap length of the water bottle bag by themselves by tying it. Also changed to a pattern knitting! Just as flexible! This coffee is for the straight type! For straight type only!! Can hold your water bottle or various straight bottles, The bottom diameter is within 7 cm, about 500ml, The bottle height (with lid) is less than 21 cm. (Water bottles and bags other than the above size need to be customized separately, please write to me) Have your own embarrassing color, you can freely match within two colors! Feel free to write me and show you color swatches ;) Material: 100% Cotton flat size: https://farm2.staticflickr.com/1765/43314658461_c06d441c0c.jpg
