I honestly currently don't have any store bought rabbit toys. All mine are things from around the house. But my buns aren't picky, and I know some are!
I use toilet paper rolls and paper towel rolls. Sometimes I will stuff them full of hay and the rabbits enjoy pulling it all out. I give my rabbits cardboard boxes of various sizes. Some big enough for them to climb, dig and hide. Some boxes small like a pop-tart box that they can throw around and dig on.
I give mine plastic solo cups. They love to throw them around. But be careful that yours doesn't chew and eat the plastic. My rabbits have never chewed on the cups. Also empty cleaned out yogurt cups they like to toss and dig.
