Fit guide
Will it fit?
The most common question about a charm, a pin or a keyring isn't what it looks like — it's whether it actually attaches to the thing you already own. So every product page on Nibbo lists three things before you spend anything: what it fits, how it attaches, and its size in millimetres. This page explains the attachment types, how to check one against what you own, and how to read the size before you order.
Attachment types
How each attachment works
Not every charm attaches the same way. Match the attachment type on the product page to what you're putting it on, then use the size in millimetres to confirm the fit.
| Attachment | Works with | What to check |
|---|---|---|
| Push-in stud | Clog-style shoe holes, including Crocs™ and other clog-style shoes | The hole's size and shape match the stud — round holes take a round stud. |
| Clip | Backpack straps and bag handles | The strap or handle is narrow enough for the clip to close all the way around it. |
| Lobster clasp | Keyrings, zipper pulls, bag hardware | The ring or loop it clips onto is open enough for the clasp to hook through. |
| Split ring | Keyrings, zipper pulls, bag hardware | There's enough of a gap to thread the ring open, and the loop it's joining fits inside it. |
| Pin back (butterfly clutch) | Jackets, backpacks, lanyards | The fabric is thick enough to hold a pin without tearing or stretching the hole. |
| Strap | Bags, phone loops | What it loops or threads through is the right width and shape for the strap. |
| Adhesive | Smooth, flat surfaces such as phone cases | The surface is clean, dry and flat — adhesive doesn't hold on a textured or curved surface. |

Before you buy
How to check before you buy
-
1
Find the fit line
Every product page has a "Will it fit?" section that lists what the charm fits, its attachment type, and its size in millimetres.
-
2
Check the attachment
Match the attachment type — stud, clip, clasp, ring, pin back, strap or adhesive — to what you're attaching it to, using the table above.
-
3
Compare the size in mm
Measure the hole, strap or gap you're fitting it to with a ruler, then compare that number to the size listed on the product page.
-
4
Message us if you're unsure
Send us a photo through the support hub, in English or French, and a real person will check the fit with you before you order.
Size in mm
Size in mm — what it means
We list every charm's size in millimetres on its product page. A tape measure or ruler turns "will it fit?" into comparing two numbers instead of guessing — here's what to measure for each attachment type.
| What to measure | How to measure it |
|---|---|
| Clog-style shoe hole | The width of the hole at its narrowest point, in millimetres. |
| Tote or bag grommet | The inner diameter of the metal ring itself, not the fabric opening around it. |
| Backpack clip opening | The width of the strap or webbing the clip needs to close around. |
| Keyring or split ring | The ring's inner diameter — anything threaded onto it has to pass through that gap. |
We don't publish typical size ranges here because clog-style holes, grommets and clips vary by manufacturer — the number that matters is the one on the specific product page against the one you measure yourself.
Questions
Fit, in detail
Do these fit Crocs™?
Our shoe charms use a push-in stud sized for the standard clog-style hole — the same hole used on Crocs™ and most clog-style shoes. Nibbo is not affiliated with, endorsed by, or partnered with Crocs, Inc. "Fits Crocs™" describes compatibility only.
Will it damage my bag?
A clip, lobster clasp or split ring is designed to attach and come off again without leaving a mark. Check the strap or handle width against the attachment first, so it isn't forced onto something too small.
Can I move charms between bags?
Yes. Clips, lobster clasps and split rings are all designed to be removed and reattached, so a charm isn't stuck to one bag, backpack or keyring.
What if it doesn't fit?
It's covered by our 30-day returns policy — see the returns page for what's eligible and how a refund works.
Do you ship to Quebec?
Yes — we ship across Canada, including Quebec, and support is available in French as well as English.
How do I clean them?
Wipe with a damp cloth and mild soap. Avoid soaking anything with an adhesive back or a pin back — water can loosen the bond over time.
