Simply unscrew the sponge head and fill the plastic container with up to 50 ml of water. Then reattach the head and drag it across gummed paper to moisten it instantly - great for sealing envelopes or attaching stamps without the unpleasant taste or hygiene concerns of licking. The clever non-spill design ensures no messy spills.
