Genuine Leather Boxing Gloves, Black, 12 oz - Brand: zhengtu (zetty) - Color: Black - Design: Velcro type - Material: Genuine leather After purchasing new, I used them to hit a heavy bag a couple of times, then stored them. There are punching gloves specifically for mitt work and heavy bag training, but recently, the trend is to use 10-12 oz gloves for mitt work, heavy bag training, light sparring, and sparring. Advantages include: - Genuine leather provides a good sound when hitting. - Can be maintained with baseball glove oil. - Can be repaired with leather if damaged. - Gloves that are too cheap are all made of fake leather (vinyl). These are perfect for those who are about to start boxing, boxercise, etc. The fact that they look a bit like Winning gloves is also a plus. The glove logo says 2020, but I purchased them around 2022. Thank you for looking.
