The craze for Postkuma merchandise in Japan is escalating. A surge in demand has led to increased instances of reselling, flooding online and offline markets. The popularity of the beloved character is unprecedented, causing toy shops and others to frequently sell out. Devoted fans and collectors are paying premium prices on the resale market to secure the coveted collectibles.

Postkuma is a popular character in Japan, capturing hearts across generations due to its adorable design and the values it stands for. The cultural impact of characters like Postkuma is significant, driving merchandise sales and consumer behavior. The resale market is indirectly supported by intense demand and scarcity of products. However, it is often scrutinized due to potential price gouging and unregulated practices, which deviate from the country's typically disciplined trade culture.

Like in Japan, the US and EU also have large markets for pop culture collectibles, inducing secondary markets for reselling when the demand is high. However, legislation against price gouging and resale regulations differ from country to country. In the US, for example, reselling is more of a common and accepted practice within its capitalistic culture.
