It makes a shaking sound when shaken♪ The tying string is made long, so please tie it to your preferred length⭐︎ Length: 5.0 cm x Width: 3.5 cm 《Important Notes》 ⚠️ For custom orders, production will begin after payment is confirmed, so it will take approximately 2-3 days to ship. I try to create items similar to the photos, but because I use natural materials such as shells, flowers, and stones, and because they are handmade by an amateur, they will not be exactly the same. ⚠️ The color, texture, and size of the product may appear slightly different from the actual product depending on your device, viewing environment, and lighting conditions such as fluorescent lights or sunlight. ⚠️ Returns and exchanges due to customer's personal reasons, such as a difference in image, are not accepted. ⚠️ While I make each item carefully, due to the nature of handmade products, there may be color unevenness, individual differences, small burrs, scratches, or air bubbles. If you are looking for the strength and perfection of a mass-produced product, please refrain from purchasing. Please understand and purchase handmade items. ⚠️ To prevent any trouble, I do not offer holds, in accordance with Mercari's regulations. #Resin #ShakaShakaKeyholder #ShakerKeyholder #Keyholder #BagCharm #Amulet #Sea #Dolphin
