No price negotiations.❌ No bulk purchase discounts (shipping discounts).❌ Please refrain from individual negotiations. You can buy directly without any rejection comments. I try to ship within 24 hours, so I don't comment until the item is shipped. Please understand. *I do not issue receipts. Set of 3, unused. VOX type aluminum machined number knob. Size: Outer diameter max. approx. 25.0mm, height approx. 16.9mm. Shaft hole approx. 6.1mm, type that fixes the shaft with a 2mm hex wrench, so it can be used with both USA and Japanese pots. (Wrench not included, please prepare.) Use for repairs and customization of vacuum tube amplifiers, tube amplifiers, stereos, antique radios, audio equipment, guitar amplifiers, and effectors, as well as for dressing up bizarre guitars. Images 5 and 6 are reference images for size. Shipping is by regular mail (no tracking number), so it may take some time for delivery (even in Kanagawa and surrounding areas, it may not arrive in 3 or 4 days). *If you let me know in the comment section before purchasing, you can change to "Click Post" with faster delivery and a tracking number for an additional 50 yen. Recycled materials are used for packaging.
