I purchased this but never used it, so I am selling it unopened. Size: Commemorative photo mount 148 x 100mm (postcard size) Selection card 7.5 x 7 cm The thick paper is 0.22cm, so it's sturdy like a postcard and has a good thickness. All corners are rounded, making it durable and safe to use. Packaging: To prevent water damage, it will be sealed in a storage bag before shipping. 1 year old 1st birthday Birthday Birthday
