Jane Rollers Upgrade

I bought my Jane loom second hand – new in the box – right around the time that the rollers were upgraded. How can I tell whether I have the new rollers or the old ones?

The new rollers are wider than the end cap. They are 2.5cm wide. Here is a picture

If you need the new rollers please send your name and mailing address to support@louet.zendesk.com. All you have to do is tell them your story and they will send them out to you.
