Might be watering them inadequately, missed the peak growing season, which is summer (most likely, though some are still growing) impatient or all of the above but I feel like that’s the size they grow, apparently I’ve read somewhere that they’re of the “ornamental” variety which means they’re that size when they’ve matured, but the picture shows a bigger size. They’re Thai Dragon Chilies. Unless I wait until next year to see if they grow bigger or to move them to a bigger pot.
I think you just have massive hands. Just compare to your scissors for reference.
Just fat hands on my part, you know what they say “the camera adds 10 pounds”, I AM the ten pounds 🤣 the scissors are small since they’re specifically for pruning I guess? That’s what my sister told me lol
