This is a cotton blue dinosaur print fabric and cotton denim fabric cushion-type cover for a disaster prevention headcover, recommended for boys. It also comes with replaceable non-slip rubber. It has a blue-green polyester lining. The denim fabric is sewn with a checkered print fabric layered on top. My grandson's commercially available cover's non-slip rubber stretched out, so I made this one and made it replaceable. Size (flat): Width: approx. 46.5 cm, Height: approx. 35.5 cm ★Please check the size of your disaster prevention headcover before purchasing. ★The denim has been washed several times, but there is a possibility of color fading, so please wash it separately. The rubber can be replaced when it stretches. Cut the stitches and replace it. It can also be securely attached by hand sewing. This is handmade by an amateur, so there may be some imperfections such as double stitching or uneven seams, but I would appreciate it if you understand and don't mind the handmade nature of the product. There may be traces of the chalk pencil, but they will disappear after washing, so please be aware of this. Returns are not accepted after shipping. It will be shipped folded.
