Cup holder for out n about nipper double

[JanieLovesLuckySocks]

Hello ladies and gents,

Now that I'm on the early morning playgroup walk, I'm looking for a cup holder (for my coffee) to attach to the handle of my out n about nipper (double).

They don't make their own, wondering if anyone has succeeded in finding a universal one that might fit?

I discovered the Babyzen Universal Cup Holder online but unsure if it would do.

Thanks in advance x
