This is a line of ponies by Funrise. They have the colors of real-life horses but their appearance is stylized, lanky with over-sized hooves. They have an early-2000’s Bratz kind of vibe. The eyelashes are rooted.
Funrise had another line called Sassy Stables that was realistic-style horses.
From package pictures on eBay, I think these are the names for these:
I haven’t confirmed that this one is Sassy Stables, but it is certainly similar in appearance. It is smaller, 4″, reminds me of a Happy Meal toy. No markings.
