I purchased this at Loft and used it to store tickets. Approximately 16 pages on the left side have been used. 【Size】 Body → H240 x W237 x D18mm Mount → Demi size, plastic-coated mount (kraft) 10 sheets (Effective mounting size/H215 x W190mm) I tried to prevent air from entering as much as possible, but it is not in the same condition as unused. Please purchase only if you understand this.
