Machinist Tire-Tread Brass & Aluminum 16-Magnet Spinner Ring

Yes. Note that our factory does NOT recommend surface silk-screen or UV ink printing on metal because smooth, chemically inert metal surfaces lack ink adhesion and peel off under thumb friction. Instead, we recommend two permanent methods on FS-069: (1) 50W Fiber Laser Engraving for monochrome logos (+$0.15–$0.30/pc, $0 setup, 100 pcs MOQ, $50 USD sample fee), and (2) Deep Laser Engraving + Color Fill for colored logos (+$0.35–$0.60/pc, 100–200 pcs MOQ, $80–$150 USD sample fee), where the laser carves a recessed cavity filled with cured enamel so the color never peels.

All magnetic and mechanical assemblies (16 pcs 4*1.2MM, N45; 1 pcs Precision Ball Bearing 27*3.95MM) are structurally enclosed or mechanically locked using industrial two-part structural epoxy (>22 MPa shear strength) and thread-locked fasteners, passing 10× 1.5m concrete drop abuse tests under US CPSC 16 CFR Part 1262 and EU RoHS 3 / REACH directives.

FS-069 is manufactured from Anodized Aluminum, C36000 Brass & 304 Stainless Steel with net unit weight of 34g and dimensions of 37.82*12.84MM. Standard factory finishes include Natural Brass Gold/Anodized Black Aluminum. Custom Pantone electroplating, PVD coating, or sandblasted anodizing is available at 300+ pcs.

We offer transparent 3-tier factory-direct pricing for FS-069: $8.37/pc for 50–199 pcs (Blank Trial / Custom Logo Starter), $7.48/pc for 200–499 pcs (Standard Wholesale Tier), and $6.79/pc for 500+ pcs (Volume Distributor Tier). Multi-SKU mixed orders can be consolidated.

FS-069 is engineered with 16 pcs 4*1.2MM, N45 and 1 pcs Precision Ball Bearing 27*3.95MM. Units are inspected for surface finish, magnet assembly, and smooth mechanical action before packing.

Yes. You can order a custom logo pre-production sample of FS-069 prior to bulk production. The custom logo sample fee is $80–$150 USD (depending on fiber laser engraving, silk-screen printing, or deep laser color-fill setup), and the sample production lead time is 10–15 days.

Beyond standard protective polybag/bubble-wrap packing, we offer three turnkey upgrades for FS-069: (1) Custom Logo Black Shockproof EVA Zipper Case (+$0.75/pc, MOQ 100 pcs), (2) Window Metal Tin Box with custom die-cut EVA foam insert (+$0.85/pc, MOQ 200 pcs), and (3) Two-Piece Rigid Magnetic Gift Box (+$1.10/pc, MOQ 300 pcs). Free Amazon FNSKU barcode & 14+ safety warning labels are included.

Custom logo sampling takes 10–15 days ($50 USD for standard laser sample; $80–$150 USD for deep laser + color fill sample). For bulk production, blank stock (50+ pcs) ships in 3–5 business days, and custom logo orders (100+ pcs) take 10–15 business days, followed by 5–7 day DDP Air Express or 20–28 day DDP Sea freight.

Every bulk batch of FS-069 undergoes strict standard pre-shipment pre-shipment inspection covering surface finish, laser logo alignment, magnet polarity lock, and drop endurance. For PTFE/bearing models, we include complimentary spare PTFE wear pads, ceramic/steel detent beads, and M2 fasteners.
