A sample kit is a sales argument you can hold. Sending the whole catalogue is a mistake; sending the right three models is a strategy.
Send three, not ten
One flagship with camera and screen, one volume fingerprint model, one entrance lock for villas. That covers the three conversations a distributor actually has.
Include the boring things
Drilling template, spindle set, printed commissioning card, and the test-report pack. These are what installers remember.
Leave out the brochure
A catalogue in the box arrives creased. Send the PDF and put the printing budget into the sample packaging.
Set the expectation
Tell the distributor what the kit costs and what it commits them to. Free samples without a follow-up call are a donation.
Takeaway
Three working models beat ten boxes on a shelf.
