Small Chinese Porcelain Vase with Red Mark

This item is a small, presumably miniature, ceramic vase or bottle with a flat base. The primary material is white porcelain, exhibiting a smooth, glazed finish. The exterior of the vessel is decorated with intricate patterns in red, blue, and possibly white or silver enamels. While the full design cannot be discerned from the sole image of the base, portions of the pattern visible along the lower edge suggest an ornate, possibly stylized floral or geometric motif. The construction appears to be machine-made or mass-produced, indicated by the uniform shape and the clear, consistent glaze. The most prominent feature is the red, square-shaped maker's mark or reign mark impressed on the center of the unglazed bottom. This mark contains red painted Chinese characters within a double-lined square border, which appears to read '三口口長', a common mark associated with Chinese porcelain, possibly indicating 'Made in China' or a specific factory/period. The unglazed rim of the base shows some very minor wear and dirt accumulation, suggesting typical handling and age, but no apparent chipping, cracks, or significant damage. There are a few small, dark specks on the unglazed foot, likely studio dust or age-related discoloration. The red mark itself shows good integrity with no noticeable fading or smudging. Given the style of the mark and the visible enamel work, the item likely dates from the late 20th century, possibly a tourist piece or decorative item. The craftsmanship, though not individually handcrafted, appears to be of decent quality for its likely purpose.
