Keychains are in PVC and usually between 3 or 5 cm. They are protected with a small plastic surface you can remove when you get them.
Attention regarding buying options!
We are dealing with some issues regarding the way this website is accepting payment. We're waiting for some return so we can hopefully fix it but it will take time.
In the meantime you can order just fine and i'll take note of your order even if the site says something went wrong. I'll just send you a Paypal invoice regarding your order instead, so be carefull to put your paypal email so i can reach you with it. =)
Sorry for the delay, we're dealy and the inconvenience with small issues from the website, so we have to send invoices this way till it's fixed. Thank you for your patience.
