I've only ever used the acrylic brush I trained with but it needs replacing. I've searched for recommendations for the best brush and keep hearing how good the CND #10 is. I am currently using Glitterbels products - does it really matter if I use a brush from a different brand? I wouldn't have even thought to ask this but I saw advice somewhere to stick with the brushes from the brand you're using. I wondered why it would make a difference.
