Please refrain from purchasing if you are overly concerned about minor details, as we cannot accommodate such requests. Also, please understand that there is a difference of a few millimeters between the outer and inner dimensions. ◉ Folded for packaging & shipping. ◉ When folding, it may be folded in the opposite direction of the assembly side, so please be aware of this. ✅ Cardboard fiber dust may adhere during the manufacturing process. Complete removal of adhering materials is difficult, so please understand and acknowledge this. Also, there may be black or gray specks, and color unevenness like stains. Please understand this as well. ☆ ※ Simple packaging; recycled materials may be used. ✅ Scheduled to be shipped via postal drop-off. ✅ Because the size is almost the same as the postal slot, depending on the type and shape of the delivery address's post, the item may not fit in the post. ✅ Please understand about corner crushing, etc., due to the impact during postal drop-off (*^^*) ⚠️ I am not a seller, so if you are a perfectionist who demands perfection in packaging, please refrain from purchasing. #Nekopos3cmA4SizeBrownBoxEmirin Emirin Shop #EmirinShop
