Product details

The Mini Bottle Keychain is printed in two parts (body and twist-off cap) with a threaded snap-fit that actually works. Inside there's room for a chapstick, a pair of earbuds, a rolled-up note, or your emergency mints.

Every unit is printed on a Bambu Lab P2S with matte PLA, gets its threads chased by hand, and is test-twisted before it ever touches a box. Split-ring keychain hardware is stainless.

Materials & care

Matte PLA is food-safe adjacent but not dishwasher-safe, so rinse with warm (not hot) water. Keep out of a parked car in summer. PETG finish is more heat and scratch resistant if you live somewhere hot.

PLA is plant-based and compostable under industrial conditions. If it ever breaks, send it back and we'll regrind it.

Shipping & returns

We print-to-order but most colorways stay in stock. Orders before 4pm CT typically ship the same day. US domestic is USPS Ground Advantage (3–5 days); international is DHL (7–14 days).

60-day returns, no questions asked, on non-monogrammed items. Monogrammed items are covered by a print-defect warranty only.

Why it's good

Engineered to survive your keys.

Threads that don't strip

Printed with 4 perimeters and hand-chased threads. Opens and closes 1,000+ cycles before feel changes.

Matte, not fingerprinty

Matte PLA hides scuffs and skin oils. The swirl on the multi-color pack is laid down layer by layer, not painted.

Stainless hardware

No painted steel rings that rust in a week. Split-ring is 304 stainless, rated 15 lb pull strength.

Fits the everyday

42mm body swallows a chapstick, mini bottle of Advil, a rolled $20, or a pair of earplugs with room to spare.

In the box.

Everything you need to clip it on and walk out the door.

Actually opens and closes.

I was skeptical the threads would hold up but three months of daily pocket abuse later, it still twists smooth. The matte orange is way better in person than in photos.

Bought 3 for my kids.

The rainbow pack is perfect for family sets. Each one got a different color, and the monogram option meant everyone knew whose was whose. Packaging was cute, shipping was stupid fast.

Tiny but mighty.

Holds a rolled up $20 and my car key backup. Took half a star off because the split ring was a little stiff out of the box, but it worked in fine after a day. Would buy again.
