Received the slippers but they are the wrong size and I can't afford the international postage to return them and they don't accept exchanges which seems odd. Interestingly I emailed them on the email address as soon as I placed the order to change the delivery address and never got a reply.
Regarding the sizes it says on the website allow 2-3cm but doesn't say - less or more which is a very large variation. I have to find someone else to give them to. The slippers themselves appear to be good so I'm sure they will be appreciated by whomever ends up getting them.
