These handles you can find on Etsy at the store from AeroMoto. They’re 3D printed, and I think they look great. The texture is just barely there. Not bad or distracting at all. The tolerances were really tight! Both went on without issue, it just required a little force to get them seated up against the lever once the original handles were removed. Just in case you don’t recognize them, they’re 737-style throttle handles for the Honeycomb Bravo. I got them specifically for when a 737-100/200 is released for MSFS. Unfortunately, I’m ahead of the curve. 
The handles themselves are nicely done. They’re way wider than the stock Honeycomb throttle “grip” thingies. They’ve got a nice, big “1” and “2” on it for Jarheads like me. 
**Note These are the handles only! If, like me, you don’t want to have to remove the stock throttle grips and swap all the time, you can get another #2 and #3 throttle lever from Honeycomb. (Lol, just not if you live in Hawai’i.) 
I had to ship mine to a flight sim friend in Minnesota and have him ship them to me.
I got the handles for a specific aircraft, too:
*This was the Aloha Airlines 737-230/Adv, N823AL, in the super cool, retro “Funbird” livery! Mmmm… shiny JT8Ds!
(She started life in July, 1985 in Deutschland as D-ABMB with Lufthansa, then moved to Hawai’i to be with Aloha Airlines in December of 1996, where she remained until 2008. At that point, after Aloha had shut down, she went to the desert in Mojave, CA, and was dismantled in 2015. She was in service for 23 years, and on the earth as an airplane for 30. RIP, old gal!)
