Customer #01

What We Learned Selling Our First Product

Our first customer was not a relative. She asked one question we could not answer, and that question became our packing checklist.

Written by All three makers

She bought a Desk Buddy for 79.000đ. Before paying she asked: 'How long will it last if it sits in the sun?'

We did not know. PLA softens at around 60°C, which a car dashboard in Saigon reaches easily. We told her honestly that we did not know, tested it that weekend, and messaged her the answer three days later.

What that taught us

  • Saying 'I don't know, I'll find out' keeps a customer. Guessing loses one.
  • Every product needs one line about where not to put it.
  • A message after the sale is worth more than a discount before it.

She has since ordered twice more and sent us a photo of the Desk Buddy on her office desk — indoors, away from the window.
