Sisters are wonderful. Right up until they’re screaming the house down, throwing tantrums and just generally being irritating; then they’re a bit less wonderful. That’s just my sister and she’s 65. But yours may be an absolute delight so make sure to get them a funny birthday card for a sister who deserves everything.
Whether it’s a sister card from another sister, a card from the bro, a special card for a little sister on their 18th or 21st, we’ve got you covered with our weird and wacky array of funny and rude birthday cards for a sister of any age.
Our wide range of unique sister cards are all A5 in size when folded and printed on 300gsm card stock. Feel free to jot down all of your offensive birthday messages as the insides are blank for you to do just that. Each card comes with a coloured envelope and all orders are sent via first class Royal Mail post. First class mail for a first-class sister. Yeh I wouldn’t be caught dead saying that out loud.
Each card and envelope are FSC certified and our packages are 100% plastic free. Barbie and Ken should be feeling pretty guilty right now.
