Three sets of casters that came with the furniture. 6 with stoppers, 6 without stoppers. Unused. I am selling them because I don't need them. Size: Insertion rod length: Approximately 2 cm Insertion rod diameter: Approximately 5 mm Total length: Approximately 7 cm Caster diameter (excluding cover): Approximately 4 cm Instant purchase OK. ⚠️Request Due to frequent problems, I will not accept "price negotiations," "selling individual items," "holding requests," or "requests for creating a dedicated listing." I am sorry, but I will delete any comments requesting these. If there is no activity, I will lower the price or remove the listing at the seller's discretion. Thank you for your understanding.
