Since handmade knit bags can differ slightly in shape, to what extent can I inspect the bag after receiving it?

For handmade knit bags, the guidance itself is divided into two parts. On one hand, it is stated in advance that because they are made by hand-knitting, shapes may differ slightly^[1]. For mesh knit bags, it is added that sizes in addition to shapes may also differ slightly^[2][3]. Therefore, until opening the box, the person who ordered cannot know exactly what shape the item coming into their hands will have, and judgment is deferred until after receiving it.

On the other hand, there is a condition stating that exchanges and refunds are difficult if there are signs of wear or damage on the collected product^[4]. Laying both notices together reveals the boundary of what can be done after opening. Examining the weave and shape in a bright place and lightly draping it over your shoulder to gauge the length falls under inspection, while filling it with belongings and carrying it out constitutes use. Knit fabric in particular is prone to widening openings or leaving stretched marks once it bears weight, making it difficult to reverse once carried out even once. Leaving it in the received condition leaves time to make a judgment, but filling and carrying it ends that time.

If you have decided to send it back, you must also calculate the costs. When returning or exchanging due to the buyer's reason, such as a simple change of mind, you must enclose the round-trip shipping fee of KRW 6,000, and exchanges that only change the size or color are also included in this^[5].

hmmm, the sentence notifying about individual item differences in advance and the sentence mentioning signs of wear are separate, but they are practically read as a pair — because rather than leaving it open for you to decide after seeing the actual item, it means to conclude that judgment while it is still in an unused state.
