Bubbles in whiskey glass

 Our glass products are handcrafted, and each piece is unique. During the production process, it's possible to observe minor mold traces or bubbles, which are inherent to the handmade nature of the glass. The acceptable air bubble size during production is equal to or less than 1mm in diameter. If the size is bigger than 1mm but within AQL 2.5, it’s also acceptable.

Please be assured that these characteristics are normal and do not affect the functionality or durability of the glass.
