8oz and 16oz Soft Blow Tasks Undamaged Black w/ Red 2-pack. High quality hammer head: Made of high quality environmentally friendly oil-resistant rubber, it offers good resilience and high wear resistance, ensuring strength and durability. It retains its original appearance even after thousands of uses. The large, flat surface allows you to hit your target every time and disperses the force of impact to prevent damage to the target surface and speed up your work. The double-sided, hard, shock-absorbing rubber head provides a gentle positive impact, which means a harmless but effective punch. Ergonomic Handle: Constructed of soft and non-slip TPR material with fiberglass shell, the handle's contoured shape and textured surface provide exceptional comfort and secure grip, while the high-strength fiberglass construction absorbs vibration and reduces fatigue. This is a quality product and I give it 4 stars.
