• Some glasses bag pictures, design the part of my bag.

• I enjoy the shape and fabric of glasses bag which could protect my glasses. 

• I think the shape of red glasses box is good but could not protect glasses avoid press.

• This is nice for glasses, but can not put in bag, include the material, occupy more space.

• umbrella bag picture (Must be waterproof)

• I would like use the shape and material inside of my bag.

• This equipment could collect water what the umbrella left. It is convenient but difficult to carry.

• Phone bag picture (Must be waterproof)

• This product could make me use phone whenever the weather is rain or snow.

• The introduction of different zippers.

• Metal zipper: A separating zipper is designed much like a conventional zipper, with two strips of sturdy fabric studded with small metal or plastic teeth that can be joined together to make a seal.

•  Nylon zipper:  In some cases, active wear jackets come with removable sleeves that detach with a zipper. This means that the jacket can double as a vest.

• Plastic Zipper: The teeth or coils are formed of metal, plastic,or synthetic material. A separating zipper is designed much like a conventional zipper, with two strips of sturdy fabric studded with small metal or plastic teeth that can be joined together to make a seal.
• 
  

• Invisible zippers, like conventional zippers, have the two strips of fabric connected at one end, but the zipper tape itself covers the zipper mechanism. They have top and bottom stops, visible only on the reverse side.

• Separating zippers are designed with a unique type of bottom stop so that the fabric tapes come apart, allowing, for example, the two sides of the front of a winter jacket to be separated for ease of use. The user inserts the bottom stop at the bottom of one fabric tape into the slider, which is on the other tape, thereby joining the two sides of the base together. The user then pulls the slider up to close the zipper. Most zippers have a differentiated front and back, buttwo-sided zippers were developed for items that are reversible, and are designed to be equally workable from either side.
