Drip reducer for existing bottle? DR Harris

I love my DR Harris Windsor Aftershave (although it was expensive!).

Problem is, there's no drip reducer like on Proraso, Stirling, etc. so I have to be very, very careful I don't pour out too much and waste my $44 bottle of aftershave.

Without putting it in another bottle (yes, I'm a packaging/presentation guy, that stuff's important to me, I like the DR Harris bottle and label), what are some options I have? Can I buy a drip reducer? Does anyone know what the diameter of the bottle opening is?

Update: I found a solution! I took the drip reducer (I guess officially they're called orfice reducers) off of a Stirling aftershave bottle (it was a small sample bottle), gave it a hot water + soap wash and rinse, and stuck it on the top of the DR Harris bottle. Voila - perfect fit!



I poured it upside down and it performs exactly like a Stirling bottle; gradual drip, but in the original bottle, just like what I wanted. I checked my full-size Stirling bottles and they have the same size "orfice reducer" by the way.

Very cool. Orifice reducer would be a great name for a band!
