Ready-to-Use Production Mold Declaration
"This model utilizes our mature ready-to-use production mold. Because smooth metal is chemically inert and surface silk-screen/UV ink peels off due to low adhesion, our factory recommends 50W Fiber Laser Engraving (+$0.15–$0.30/pc, $50 sample) or Deep Laser Engraving + Color Fill (+$0.35–$0.60/pc, $80–$150 sample)."
FS-149 Dual-Bearing 8-Ball Square Frame Kinetic Fidget Spinner — Mechanical Architecture, Logo Customization & Packaging Guide
Manufactured on our mature ready-to-use production mold #149 ($0.00 tooling investment), the FS-149 Dual-Bearing 8-Ball Square Frame Kinetic Fidget Spinner is built from Die-Cast Zinc Alloy (Zamak #3) with precision outer dimensions of 35.5*35.5*19.5MM and a calibrated hand-feel weight of 72g. Every unit is assembled and inspected at our Fuzhou Industrial Zone export hub prior to international dispatch.
1. Internal Haptic & Acoustic Mechanism Calibration
The internal drive system integrates Non-Magnetic (Pure Mechanical / Bearing Action) paired with 8 pcs 3MMHardened Steel Detent Ball , 1 pcs Micro Bearing Ø12.7*Ø6.35*4.7mm,1 pcs Large Bore Bearing Ø23*Ø17*4mm. All neodymium magnet pockets and bearing seats are mechanically locked and bonded with industrial structural epoxy (>22 MPa shear strength) to guarantee zero magnet detachment under US CPSC 16 CFR Part 1262 drop tests. Standard factory surface finishes include Satin Pearl Chrome.
2. Custom Logo Branding & Private-Label Options ($0 Mold Fee)
- 50W MOPA Fiber Laser Engraving (Monochrome): MOQ 100 pcs · $0.00 setup fee · +$0.15–$0.30/pc unit cost. Micron-ablates permanent metallic/white contrast marks that never peel or fade.
- Why Silk-Screen / UV Surface Printing Is NOT Recommended on Metal: Polished and plated metal surfaces are ultra-smooth and chemically inert; surface inks lack adhesion and peel off under thumb friction.
- Deep Laser Engraving + Enamel Color Fill (Recommended for Colored Logos): MOQ 100–200 pcs · $0.00 laser setup · +$0.35–$0.60/pc unit cost. Laser-carves a recessed cavity into the metal and fills it with cured enamel so the color never peels off.
- Paid Custom Logo Pre-Production Sampling: Standard Fiber Laser Sample = $50 USD · Deep Laser + Color Fill Sample = $80–$150 USD (10–15 days lead time; free 12-hour digital proof prior to sampling).

Frequently Asked Questions — FS-149
Because FS-149 utilizes our mature ready-to-use production mold (#149), the tooling and mold fee is $0.00. The wholesale MOQ is 50 pcs for blank stock orders and 100 pcs for custom 50W Fiber Laser Engraved or Deep Laser + Color Fill logo orders.
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-149: (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 (Non-Magnetic (Pure Mechanical / Bearing Action); 8 pcs 3MMHardened Steel Detent Ball , 1 pcs Micro Bearing Ø12.7*Ø6.35*4.7mm,1 pcs Large Bore Bearing Ø23*Ø17*4mm) 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-149 is manufactured from Die-Cast Zinc Alloy (Zamak #3) with net unit weight of 72g and dimensions of 35.5*35.5*19.5MM. Standard factory finishes include Satin Pearl Chrome. Custom Pantone electroplating, PVD coating, or sandblasted anodizing is available at 300+ pcs.
We offer transparent 3-tier factory-direct pricing for FS-149: $9.94/pc for 50–199 pcs (Blank Trial / Custom Logo Starter), $8.89/pc for 200–499 pcs (Standard Wholesale Tier), and $8.07/pc for 500+ pcs (Volume Distributor Tier). Multi-SKU mixed orders can be consolidated.

Yes. You can order a custom logo pre-production sample of FS-149 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-149: (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-149 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.
