The crystal has undergone a proprietary treatment that allows wine to aerate in just two to four minutes. More importantly, the glasses will never lose their ability to improve your best wines and can be washed just like other glasses -- no special treatment required. Hand-blown of lead-free crystal, these glasses are extremely durable. Taste for yourself, the proof is in the glass. 9 1/2"H, 24 oz.
