I'm sure this polymer powder product is similar to that formerly available as "Power Grip" from Ajay, which is especially good for gripping a tennis racket --- but the price of $10.95 is horrendous!! Fifteen years ago, Ajay's product sold for $1.20 to $1.50 at retail outlets. A price of $5 (preferably less*) would still be pretty stiff, but a helluva lot more reasonable.

*3.00 should be the maximum at this time. Even top of the
line athletic socks have only doubled in price during the
same interval.
