And I thought paper clips would do the trick lol. The thickness was ok and it even slotted in the little holes, which prevented it from moving around, but it was almost impossible to straighten the clip even with a plier. Birthday sparkers? Would be stronger but not sure if too thick and also has a long bump (where you light up the candle), if that part can be scrapped off clean, and if the magnet can hold it, it may do the trick? I might have a few left and if I can find it take a closer look.
