I've tried to use a cheaper brand but the smell gives me a headache and they are hard to erase

Expo is usually the leading brand in dry erase markers but this time they came up short

The expo brand is an excellent brand

Love this brand

Great brand, works well.

Love these markers for working math problems, the only brand I trust.

they works as they are supposed to
