The Super Expanders from SENSAS is a great addition to our range. These Super Expanders can be prepared without a pump and nevertheless have the perfect spongy structure of expanders. Place the expanders in a bait box, add water until the pellets are just covered, then soak in the fridge overnight. You have perfect pellets every time. The packaging can be resealed, so you can prepare your pellets for each session as needed.
