1) Collab context & internal references

When teams mention Cookies × The Freak Brothers, they usually mean a brand collaboration theme plus a “Liquid Diamonds” positioning. If you’re vetting compatible empty hardware or running a look-alike packaging program for private label, start with internal category pages for parts and formats:

• Brand family context: cookies x the freak brothers
• Two-flavor switchers: dual chamber vape
• Status displays & counters: LED screen vape
• Capacity class: 2g disposable vape pen
• Comparable build for benchmarking: Choices Lab

2) How to choose the right 2 g hardware

Core decisions

• Chambering: Single vs. dual. Dual enables A/B flavors or blend logic and supports “Liquid Diamonds + Live Resin” themes. Check that the selector (button, slider, or firmware multi-click) is intuitive and locks during transit.
• Display: LED screen units can show A/B state, battery %, puff counter, and preheat timers—useful for QA and RMA reduction.
• Power & charging: 300–400 mAh with USB-C is common. Confirm cell vendor, C-rate, and cut-off thresholds; require a shipping state-of-charge policy.
• Thermal path: Consistent coil spec and airflow geometry limit hot spots and condensate, especially in dual-path mouthpieces.
• Housing & tolerance: Check mouthpiece fit, seam uniformity, slider alignment, and gasket compression to reduce leaks in freight.

QC acceptance sampling (quick)

• Cycle A→B (or A→B→Dual) 10× without missed states; confirm on the screen each time.
• Preheat timer accuracy within ±10% of printed spec.
• USB-C charge handshake works on 5V/1A bricks and common power banks.
• No binding on selector; mouthpiece stays seated after 10 pocket-drop tests.

3) How to verify licensing & safety documents

Licensing (brand/retail chain): Use an official state license-search portal to confirm the named entities (manufacturer, distributor, or retailer) are active and in good standing. Capture screenshots or PDFs for your procurement file, and reconcile legal names against invoices and packaging. (If operating in California, use the DCC tool.)

Battery & electrical safety: Request evidence that the platform has been evaluated to the spirit of UL 8139 (electrical, heating, battery, and charging systems for e-cigarettes) and that the exact cell/pack carries a current UN 38.3 Test Summary. These are foundational for safety design and transport readiness.

Air transport compliance: For air freight, confirm packing instructions and marks/labels follow the current IATA Lithium Battery Guidance (2025). Require documented SoC policy and shipper declarations from your forwarder.

4) How to order in bulk with fewer risks

MOQs, case packs, and lead time

• MOQ & assortments: For theme launches, split MOQs across A/B shells or colors while keeping the same internal platform for easier QA.
• Master cases: Use impact-rated outers and tray inserts; specify orientation arrows and anti-scuff sleeves for screen models.
• Lead time planning: Buffer 7–10 days for incoming QA (selector cycling, screen checks, and five-unit teardown) before the creative team finishes pack-outs.

Paperwork to collect (save to PO folder)

• Commercial invoice with accurate model, cell vendor, and HS codes.
• UN 38.3 Test Summary PDF referencing your exact cell/pack model.
• UL 8139 evaluation evidence (or letter of conformity/test report excerpts).
• Forwarder’s IATA DGR compliance notes and shipper’s declarations.
• Where applicable, a link or screenshot from the state license portal for the seller of record.

Receiving checklist

• Randomly sample 3% (min. 20 units). Log A/B switching, preheat timing, and battery indicator behavior.
• Inspect mouthpiece seals and slider tracks for burrs; rework or quarantine if failure rate >1%.
• Record serial/lot and photograph outer labels before pallet teardown.

5) FAQ

Can I mix dual-chamber and single-chamber units in one order?

Yes, but keep the electrical platform consistent. Mixing platforms makes QA and RMA harder.

Do LED-screen models reduce RMAs?

Often, yes—screen feedback (battery %, preheat, A/B state) helps customer support triage issues and reduces needless returns.

What if we operate in multiple states?

Keep a per-state compliance folder (license lookups, labeling rules, and freight notes) and update it quarterly alongside your supplier documents.
