A greeting card featuring a cute hard working battery, with your own message on the front and/or inside.
Gloss coated on the outside, matt on the inside so that it's easy to write on. The envelope is plain brown.
A versatile card you can tailor for lots of different occasions! This physics themed design, suggested to me by a high school physics teacher, could be for a science teacher or student. It could be used for a retirement or new job. Or it could be used to thank a carer, helper, trainer or tutor. You could use a message like "Thanks for all your hard work and energy!"
You can personalise the message on the front of the card, and if you don't want the card to be blank inside you can also specify the message you'd like displayed there.
