It's not a very practical shape for toothpicks, it's too wide, once it began to get empty they would fall sideways and be hard to get out. It's also not a shape you could arrange flowers in, even violets, you would have to ram them in completely upright. I know some of the frogs are designed for short stems but they are meant for arrangements of flower heads, and you wouldn't get more than two in one of these.
It is however a known shape for cigarette holders cf Royal Brierley pattern no 65669
