These optional inserts are for the VinGardeValise Wine Suitcase that you can purchase from use on Amazon. The magnum bottle insert was designed to allow wine travelers to replace one (or more) 2-bottle inserts with an insert designed to carry a magnum or similar large format bottle. Other Information: Packing the magnum insert: - Insert your large bottles into the cavities neck first at about a 45 degree angle, then the bulk of the bottle should be pushed gently into the open cavity. - Removing and separating the foam inserts - The first time you remove the foam module(s) to allow for other uses of the suitcase, it may be necessary to cut apart the three 2-bottle modules. This can be done (carefully!) with either a box cutter, Exacto-type knife or other similarly sharp instrument. Simply gently stretch apart the pre-cut modules at the seams and sever the remaining foam connections with the sharp implement. - That should do it. Based on your travel needs, you can then place one, two or all three modules in each side. - The foam modules with the rounded corners always must go on either the inside or outside "slots" to properly fit the contours of the suitcase; the one with no rounded corners goes in the middle. Cleaning: Your inserts consist of a high-density closed cell foam. This makes cleaning and maintenance easy and hassle free. Simply wipe the inserts down with a damp cleaning cloth.
