Never used. I purchased it about 5 years ago, but it has been stored in a cloth bag in a dark place. The bag is a little wrinkled. Please refrain from purchasing if you are concerned about home storage. Width 18.5cm Height 12.5cm Depth 3.5cm Material: Main: 55% Cotton 45% Polyamide I think it can be used by anyone. It will be returned to the included bag and shipped in a cardboard box.
