When bubbles or wave marks are visible on the surface of the glass, should I submit an exchange request for a defect or for a simple change of mind?

Diagonal lines, wave marks, and fine bubbles do not qualify as grounds for an exchange due to defect, but an exchange or return through a simple change of mind is possible^[1][2]. Kimura Glass states that due to the nature of handmade work where craftsmen shape the products directly, wave or diagonal grain, fine bubbles or protrusions, fine scratches, and dents may remain on the glass surface^[3].

The rim mentioned in manufacturing variations refers to the upper circumference of the glass where lips touch, and the stem refers to the slender leg part connecting the base and the bowl. Even for models of the exact same specification, hand-blown and finished glasses differ slightly in the curvature and end finishing shapes of this rim or stem^[4].

The brand considers these phenomena and shape differences to be characteristics naturally appearing in the glassmaking process and does not deem them defects^[5][6]. Therefore, if you wish to exchange the product or receive a refund, you must proceed by selecting the simple change of mind exchange and return procedure rather than submitting it as a defect^[7].
