Thank you for viewing. This item came with a used purchase. I am unsure of the specific use or storage conditions, so please examine the photos carefully. I have included a ruler in the photos to show the size of the worms, etc., so please use it as a reference. The ruler is not included. There are limited photos, but please request if you need more. Due to the nature of this item, please understand that it is sold as-is, with no returns or claims.
