I havent tried the magnetic ones but i presume they can be very dangerous. Remember nowadays no children toys carry magnets for a reason. They would be swallowed, attach themselves inside the body and pinch organs.

Cut the tip of the syringe, take de plunger off, put it on the opposite end. There you go. You need now a stop to hold the preassure. I use old toothbrush handels. It’s the best vacum pump I’ve ever tried. You can meassure the intensity by how deep the plunger starts. Enjoy

Get two needless syringes, cut the tip, flip the puller and fashion a stop out of something. Best suction, cheapest, infinite widths and gives better defined nipple edges.

Nice! It depends and what shape of nipple you want to achieve, you can try smaller ones to get button like nipples. Do you use stoppers to keep the pull force?
