Thank you for viewing! (^_^*) This is a cushion-type cover for a disaster prevention headcover. It's the type that you put the headcover in and take it out using Velcro (1 place, 2cm wide, 15cm long). The elastic is 2cm wide navy blue with a red line. It's unlined and made of a single layer of double russell mesh fabric. ☆Size (flat) Approximately 32.5cm long x 32.5cm wide, 4cm gusset * A silver disaster prevention headcover (27 x 28) fits perfectly. ☆The product will be folded small and compressed for shipping, so please understand that there may be some creases. This is a handmade item by an amateur. I will make it carefully, but there may be some slight size errors, distortions, and loose threads. Thank you for your understanding. ☆The color may be slightly different from the actual product depending on the lighting. ☆Please refrain from negotiating a price reduction.
