Fun for monsters of all ages
Hi, I'm Jason Holladay, the artist behind Periwinkle Products. My wife and I dreamed up the Little Monster Mailer Club because real mail is fun at any age, and mail from a monster is even better.
Every month, a new monster shows up with a fun story, a few silly surprises, and a little lesson worth keeping: be kind, try again, make new friends, dream big. Color it, solve it, stick it on the fridge, or read it together at the kitchen table or at bedtime.
For kids of all ages!
Be Kind. Be Silly. Be Your Monstrous Self.Questions
Who is the club for?
Kids of all ages! Sign up a child, a grandchild, a friend, or even yourself.
When will my first envelope arrive?
Envelopes mail at the beginning of every month. Sign up by the 15th and your first envelope mails at the beginning of next month. Sign up after the 15th and you'll start the month after. Join by November 20th and your very first envelope mails at the beginning of December, at the launch special price of just $8 ($13 USD international). After that, it's the regular $11 a month ($16 USD international).
Do siblings get a discount?
Yes! Sign up two or more siblings at the same address and each one is 10% off, every month. Each sibling gets their own envelope with their own name on it. During the launch special, each first envelope is just $8, and the 10% sibling savings start with the second envelope.
How long does delivery take?
US envelopes usually arrive within a week of mailing. International envelopes can take 1 to 4 weeks.
Can I give the club as a gift?
Yes! Choose any plan: 3 or 6 months paid once, or monthly until you cancel. Tick "This is a gift" to add a short note, then enter their mailing address at checkout. We'll print your note on a card in their first envelope, and every envelope goes straight to them.
Can I sign up more than one person?
Yes! Everyone gets their own envelope with their name on it. If they live at the same address, add each one to your cart with their own first and last name and check out once. If they live at different addresses (say, grandkids in different homes), place a separate order for each address.
How do I cancel?
Monthly plans renew automatically until you cancel. You can cancel anytime from your account page or the Manage My Subscription link at the bottom of our site. Cancel by the 15th and you won't be charged for the next envelope.
What if an envelope doesn't arrive?
We're sorry! In the US, if your envelope hasn't arrived by the end of the month, email us at support@periwinkleproducts.com and we'll send a replacement. For international mail, please give it 4 weeks before reaching out. It's also a good idea to double-check the mailing address on your order confirmation.
What information do you collect?
Just a name and a mailing address, so we can send the mail. We never sell your information, and you can ask us to delete it anytime at support@periwinkleproducts.com.
