Set of 6 Usurai thin tumbler glasses
The Usurai series is the thinnest, finest, machine made glass in the world. Made in Japan with extreme care for detail that seems to be the norm in the great Japanese companies. Featuring the Hard Strong (HS) glass-strengthening technology developed by Toyo Sasaki Glass in 1967, this glass is more durable than standard glassware and certainly stronger than hand made glass of this delicate thin walled kind.
The process that is used to create these elegant glasses is much like hand blowing, only the blowing itself is done by a huge steaming and hissing machine that could have escaped from a science fiction movie. This is unlike most affordable priced glassware that is made using a casting method, leaving a rather unsightly seem across the finished product.
These tumblers are wonderful for drinking (mixed) spirits over ice, particularly a big round ice ball as they do in Japan.
