Request batch photographs and a packing list prior to shipment.
Keep certificates current and filed against the exact model name.

Frequently asked questions

How can leakage in Passage 4 shipments be reduced?

Use sealed inner trays, keep cartons upright and allow a settling period before retail display.

Do you support long term supply agreements?

Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.

Can packaging be adjusted for our market?

Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.

The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.
