The item in hand is an older design from the high-end line that was available from the mid-2000s to the early 2010s. Compared to the current, new specifications, there are several clear differences reflecting the evolution of the times. * Delicacy of the design: The current models have switched to a more vibrant and pop-like color transfer technique to accommodate mass production, so the older models are perceived as "more delicate and beautiful." This is due to the adjustments made by the artisans of the time and the fineness of the designs themselves. * Painting on the inside of the tea strainer: Current products prioritize convenience and a "visually stunning from any angle" aesthetic, tending to include patterns on the inside. However, the previous models prioritized the appearance from the outside and did not have any painting on the inside. * Engraving on the underside of the lid: Recent products now have text and logos on the underside of the lid. The absence of text is a characteristic of the period when the underside was designed for cleanliness as a "tea strainer rest" and featured a simple design without unnecessary decoration.
