Description:
Get a snug stretch on your sack with the Oxballs Ultracore Ballstretcher + Power Lock Ring!
The Ultracore system is made for those big ballers who love the most bag gripping stretch! This two-piece set gives you the comfy pull you desire. The Core ballstretcher has an hourglass-shaped inner smooth tunnel that wraps your sack with a medium firm squeeze. If that’s not enough, add the Axis power ring on top to get an extra squeeze for maximum stretch!
The Core stretcher has a ribbed middle exterior and the Axis ring has a matching ribbed inner ring. These two fit perfectly together so stack them up for the best fit and maximum stretch. Both are made from Oxballs’ extra soft Plus+SILICONE blend so it keeps the grip with a smoother velvety, rubbery feel. You get a comfortable grip for more play.
The Ultracore ballstretcher rings are super easy to use. Just lube up your junk with some water-based or silicone lube – both are safe to use, stretch the Core and drop your bag in, adjusting it’s position for comfort. For that extra squeeze, stretch the Axis ring over the Core and sit it in place on the Core’s middle rib grips. Then moan away as you feel the sensual tug on your sack.
Keep it clean too! Remember to wash your rings before and after every use with a toy cleaner or warm, soapy water and let them air dry. Store separately.
Feel the squeeze with the shockingly superior Oxballs!
