Birkin Empty GIFTWRAP GIFT BOX. + TISSUE Paper Ribbon Authentic. 1 Empty Gift Box (damaged). I estimate is the largest size of the bag that would hit here. It's probably 28 cm.
Possibly 30 but you have to measure your bag with the handle because they handle has to fit into the box comfortably. When calculating the size you need for your bag, please do not forget to add the height of the handle so you have to measure from the bottom of the bed to the top of the handle add at least 2 cm and then check at eight is less than 35 cm!!
