Also, due to the nature of the material, small black spots, pinholes, and color unevenness due to glaze accumulation may be visible, but please enjoy them as one of the natural characteristics of ceramics. In addition, stacking may be difficult due to individual differences in the inner diameter of the cups. Please contact us if the issue is significant. ※ This product cannot be stacked with the Stacking Mug Latte White or Stacking Mug Coffee Black due to differences in the inner diameter of the cups.
