A ball flask is the evil brother of ball weights. Made of hollowed 316L surgical steel the ball flask can be attached to the balls and imprison them inside a steel canister. For more fun the flask has a removable base plate that allows you to connect more weights or an optional ball crusher accessory that can be screwed into place and apply a bit of fun to his encased balls (See our first related item below).
Dimensions are 1 2/5" inner diameter, 3" outer diameter, 3" depth and a total weight of 39 ounces (over 2 pounds!)
This is really good stretcher.I enjoye wearing it under loose pants.
Have trouble keeping pubic hair from getting in way when connecting pieces.
Opening for balls has a sharp edge which should be rounded off.
Has nice hook on boottom for adding extra weights.
Very good quality.
Would recomend it as a good buy.
