These Clever "Shark Tank" Products Are $25 and Under

If you're a golfer who likes your clubs, shoes, and balls to be spotless, you'll need a pack or two of the GolfERASERS Instant Golf Erasers ($15 for a pack of six). It's a reusable dual-sided sponge that's best used wet. One side has a rougher scrubber, and the other is a softer sponge. You don't need to add much pressure when cleaning — the eraser does all the work for you.
