My eldest boy is a couple of months off being 3, although he will sit down and paint with me every now and then he’s not really that interested in them (3 yr olds have pretty short attention span)... I would say they’re definitely not recommended for kids this age, with all the small parts etc... but I suppose it depends on the child, all 3 yr olds are different. Personally I wouldn’t let my kids play with minis unsupervised, but my kids are little terrors and we would end up with them everywhere
