Greetings card.
 
Pfft, stop, you're making me blush.
 
Sustainably sourced high quality 340gsm card.
Blank inside so you can fill it with anything from sweet nothings to unsettling sea shanty lyrics. 
Comes with a lovely white envelope that's green inside (VERY exciting) and a teeny tiny A Little Hat Friend sticker to do with as you please.
Always packed and posted with 100% recyclable packaging.
