You get the amazing CORE ball stretcher- it’s got outer ribs for super long stretch: it stays taller on your sack with more padded grip in the middle for a fatty bag-squeeze. You also get the rib-gripping rubbery AXIS power-ring its got channel ribs inside that morph with the outside ribs on the CORE stretcher. CORE ball stretcher is an amazing ball stretcher on its own- on your nuts the inner smooth tunnel wraps your sack with a medium fire squeeze, but add AXIS power ring on top of the cogged CORE and get the most MAX BAG SQUEEZING.
