This appears to be a gift received after purchase at a local department store. Although the items are unused, there are quite a few issues... lol

First, the Tempura has a film on both sides that looks like hardened oil.
This is a rust prevention treatment applied from the beginning and seems to be fine for practical use.
Next, one of the Chopsticks has a slight warp near the tip.
This is likely from the beginning.
Also, there is a blackish discoloration, about 3mm in diameter, near the spout of the Dipping Sauce Dispenser.
Similarly, the lid of the Dipping Sauce Dispenser has a chip on the rim.
These are clearly initial molding defects, as they are covered with glaze.
Furthermore, the Dipping Sauce Dispenser Saucer has several scratches on both sides due to molding defects.
And the Small Plates have scattered blue dye splatters and pooling.
While none of these issues are expected to affect functionality or practical use, please be aware that the finishing is not very meticulous, and there may be other overlooked imperfections.

The box also shows considerable age-related deterioration, including dirt and deformation, and has the words Tempura Set written in two places.
