The wax doesn't fit in the tin
If your creation doesn't quite fit in the tin, don't panic! It just means you may need to find an alternative container to use to get it back to us.
If you have another container to send your wax back in, this is absolutely fine. This could be an old jewellery box or anything similar. As long as it's secure and well protected, it's fine.
If your container still fits in the envelope, this again is fine to use.
Make sure that you pop your Unique Kit ID and Casting Code on the container somewhere so that we can identify your piece when we receive it.
