Olga’s Offensive & Delightful ‘Great Sister’ card is the perfect alternate card to those “other brands” with their cute, sugar-sweet verses. Olga says it exactly like you’re really feeling with no holds barred! The cards are bold on the outside and blank on the inside so you can add any text you’d like. Here you will find the right card for birthdays, weddings, congratulations or just to tell someone you’re thinking of them. But be warned – many of these are NSFW (that’s Not Safe For Work, for those who didn’t know!) Each card includes an envelope that matches.
