We purchased this item to protect an expensive pair of sunglasses while traveling to the Caribbean for 7 days.  We have had sunglasses damaged by luggage carriers before and did not want to have to buy more at the destination.  In fact our luggage was torn and blacked upon arrival, but the hard case was intact and our Maui Jim's safe!!  We are very please and will recommend this item to anyone who needs to protect their eyeglass ware of any kind.  Thanks for such a fine product.
