I am also selling similar items, but this one is slightly larger. ★ Size: 100 ★ Length: Approximately 67cm, Width: Approximately 23cm, Height: Approximately 14cm ★ Thickness: Approximately 5mm ★ "Fragile" printed in red on both sides. ★ This is a set of 20 sheets, enough for 20 boxes. ★ The listed price is for 40 sheets, enough for 40 boxes. ★ I will wrap the entire item in bubble wrap for protection against rain before shipping. Although it's rare, there is a possibility of some damage or dents during shipping. Thank you for your consideration.
