I first came across Olive Box on Twitter. Set up by Grace Kang, former buyer for Bloomingdales and Barneys in New York. Olive Box is a monthly subscription where you will receive a box full of delightful goodies from cards, to gift tags to artwork, and each month has a surprise theme. If you've had a bad day at work, imagine coming home to this little beauty?! It would certainly cheer me up!
Other 'notable' subscriptions ('scuse the pun!) are Nicely Noted, also a US based company, who supply you with 3 beautiful letterpress cards per month with stamps....
And last but not least, Mercier Beaucoup - also US based, but appear to ship internationally! Again a beautifully curated selection of cards for all occassions.
Could you be tempted to sign up to a stationery subscription?! Also, if you haven't already had a peek, the current issue of 91 Magazine has a bit of focus on stationery so be sure to check it out if you're a fan! (NOTE: the next issue will be out very soon! make sure to subscribe to receive it straight to your inbox!)
