- Q: Aren't you afraid of a UBM during the flight?

(3 hours later, in the aircraft, with tiny, always closed and/or uncomfortable toilet)

UBM 

An Unexpected Beautiful Moment.

The answer for those that truly seek and look beyond the surface. The product of revealing the unexpected beauty in life – making one's richer.

A #UBM is an invitation to truly see and experience. It's when you meet someone and this person becomes special, it's when you have an experience for the first time and end up enjoying it... the passport to every day discoveries.

I went to the bar around the corner, met an interesting girl/guy (or both), came back to my place, and had a UBM.

I went to Coachella and heard this band called St. Lucia for the first time. It was such a UBM!

Well, I saw this Issey Miyake jacket in Tokyo, it was a true UBM. I knew I needed to bring it back with me.

I went to Cuba with very low expectations; however, I had a UBM. The party was sick, the food was great, and my Italian lover hot.
