The PE case series has been combined with reflective material to allow you to see the inside. This series is made of different materials on both sides of the PE and reflecting surface that you can see inside. You can see the contents from the PE side when you want to see the contents, and when you want to hide the reflecting surface on the front side for a blind. In addition, the reflective surface reflects light from headlights or lanterns, especially when camping, increasing visibility at night. You can also connect the shoulder strap (sold separately), so it can be worn diagonally. Reflects well at night when traveling on a bicycle or motorcycle, increasing safety. Once stored inside, close the Velcro closure, wrap around the mouth and fasten the buckle. The mouth is closed and the buckle is easy to carry as a short handle. The roll-top opening and closing can be adjusted according to the amount of items inside, so the contents can be stored perfectly according to the capacity so that the items cannot be played. The front of the opening has been updated to make it easy to open and close the Velcro part. It is also convenient to hang your hand as a simple handle when you put things in and out of the inside. Accented with weekend(er) color woven tape. Even small wet items such as planter cover, laundry bag, grocery shopping, childrens toy storage, tableware storage at camp, summer water play supplies etc. It also has a chape, rough texture that gives this product a sense of quality.
