For large-volume orders, you can contact customer service to modify the shipping fee. For products that require custom logos and cannot be returned, please contact our customer service for further discussion Warm reminder: As grinding cores are consumables, we do not accept trial grinding! Once used, they cannot be resold. Non-product quality issues do not qualify for return or exchange without reason, please be informed Regarding the Static Electricity Phenomenon: The manual coffee grinder has static electricity reactions during grinding, especially noticeable in winter. Coffee grounds can stick to the grinder cup walls and under the grinding plate. Therefore, baristas have a habit of tapping the grinder after grinding coffee beans to remove the stuck grounds. Static electricity reactions are common in manual grinders. I hope this helps educate you about a natural phenomenon. Please respect science. Thank you!
