I believe this is Penang Pewter from Malaysia. It's a set of 5 shot glasses made of 97% tin. While there are some minor dents from storage, they appear unused. Tin is said to mellow the taste of alcohol and water. Please try it with tequila, whiskey, etc. Weight: Approximately 58g per glass Height: Approximately 52mm Top diameter: 44mm Bottom diameter: 34mm Please check and assess the photos.
