It is safe to say that the vast majority of girls who go out on hen parties intend to get rather drunk, so you can now guarantee that you can by having your own shot glass to carry around with you.
This particular shot glass has several features which make this stand out from other glasses. For one, this has a beaded necklace attached so you won't be able to lose it, for that particular benefit it also glows in the dark and last of all, but by certainly no means least, it has a willy shaped mould inside.
