I use a wide range of markers, from several pumps, a Tiberius 8 pistol, an AKA Viking, or a TM7.
Lower cost than some other gloves out there
Lack of adjustment straps
This glove is perfect, if you find the one that fits your hand perfectly.
Functionally speaking, these work well at what they do. There is mesh material on the fingers (between other fingers) and it does work rather well at breathing. This prevents sweaty palms from forming over the day.
The biggest downside, to me, is the sizing. I ordered the biggest they had (XL) and most other gloves in that size from other producers fit me well. Not so with these, I had to struggle to get them on the first several times. Now that they're broken in, it's a lot of effort, but it is doable and they don't pinch my hand as much.
If you have smaller hands, order them as you see fit. If you have bigger hands, I'd recommend finding another glove. When I have the spare funding, I'll be replacing these because they don't fit me well.
