Made for little days

Their own latches to work on
When every cabinet lock and door latch is a target, give them a cube made for it: a tap to turn, a lock and key, a bolt to twist.

Small cube, lots of sides
The wooden body is about 2.2–2.4 in (5.5–6 cm) per side, with activities on every face. Some parts may vary slightly from the photos.

Twenty minutes to cook
Set it on the table or the kitchen floor and let them work the lock and bolt while you get dinner going.

Questions
Good to know
What age is it for?
Ages 3 and up. It has small parts like keys, so it isn't for younger toddlers.
How big is it?
The wooden cube is about 2.2–2.4 in (5.5–6 cm) per side, plus the parts that stick out. It's palm-size, not a large board.
What can they do on it?
Turn a tap handle, spin a spinner, lock and unlock with a key, twist a nut along a bolt and slide a latch.
Will it match the photos exactly?
Some activity parts may vary slightly from the photos.
Does it need batteries?
No. Everything is hands-on, with nothing to charge.
How much is shipping?
Shipping is free on every order within the United States, with no minimum spend.
How long will my order take to arrive?
Orders are prepared in 1–2 business days. Most orders arrive within 2–4 weeks, and some items can take up to 30–60 days depending on the item, your location and busy seasons. Shopping for a shower or a due date? Please order early.
How do I track my order?
As soon as your order ships, we email you a tracking number. Tracking can pause for a while in transit, so a gap in updates doesn't mean your package is lost.
What is your return policy?
You can return items within 30 days of delivery if they are unused, unwashed and in their original packaging. Defective, damaged or wrong items are free to return. For change-of-mind returns, a $10 return shipping fee and a $10 restocking fee are deducted from your refund.
Is there anything I can't return?
For your baby's health and safety, we can't accept items that go in the mouth or against the skin once they've been opened, used or washed. Unopened items in sealed packaging can be returned as normal.
