I'm reaching out to inquire about your caster wheels featuring swivel functionality with a break. I'm particularly interested in those with a steel construction and a red polyurethane coating. If you could provide me with more detailed specifications, including pricing and availability, that would be great. Could you also let me know about any minimum order quantities and lead times for shipping? I'm looking to make a decision soon, so a prompt response would be appreciated. Thanks in advance!
