A pack of gold foiled card cut out letters and numbers. The letters are around 1cm square, varying a little up and down depending on each letter. They're not adhesive so will need a little glue on the back or could be combined with something else decorative like stitching to fix them down.
 
A pack of these are part of the September/October 2023 Custom Card Kit so if you subscribe to the Custom Card Kit only order this if you'd like an extra pack as one will already be in your kit box.
