CASIO G-SHOCK DW-6300-1B Watch straps. In great condition, even with the original spring bars included. It could use a little clean in between the strap holes, but given the resin material, that would be a super easy job. This is an original part and an item which comes from my personal DW-6300 (one of my favourite watches to this day), the watch case of which was sent into Casio for a repair only to find out they did not stock the parts for that repair anymore, therefore they offered me a discount in exchange for the watch - therefore leaving me with the just the straps. If you have any questions, do not hesitate to ask!
