I have been using these gloves for about 4 years. I think the size is normal. At the beginning of use, when sweat is applied, it is sticky that it is processed inside, it is good to wash once. Dalai powder (lathe cutting) is also hard to pierce and is strong against oil. But, even if there is any cracks, it splits easily. I used a lot of oil-resistant gloves but this was the best for me. Summer is quite hot.
