These are compatible spring bars, almost the same size as the genuine spring bars for the Frogman DW-8200 series and GW-200 series. The common spring bars sold cheaply in sets on Am◯zon etc. have a shaft diameter that is too thin and won't fit G-SHOCKs. These are made thicker to fit G-SHOCKs, so they can be used without any problems. How about these for those who have lost their original ones or want spares? Use them for repairs! *Since this product is priced at the limit, we cannot offer a discount for single items, so please consider the current price. #Click here for related G-Shock products in our shop♪ Please refrain from purchasing if you cannot complete the transaction within 48 hours of the product's arrival. *Please also read the profile before purchasing.
