Add 1 hydration foam with amazing hydration performance with this pack. Only for Painter v2.

The special foam is naturally anti-fungal. No anti-fungal chemicals are added to the foam and the effect will not wear out over time. So no bad smell after a few days, even if it has not been kept in the fridge.

Lasts a long time, you just need to rinse it off with fresh water every now and then.
