decorating a christmas tree with balloons

I think we originally bought them at John Lewis USA for ourselves and our cat’s initials. We’re having a baby, so ideally we need another John Lewis. I don’t seem to be selling them anymore. I’d really appreciate any help.

To clarify: John Lewis doesn’t stock the letter E, and I looked it up. There must be a supplier somewhere.

I’m in the US, and Target sold very similar models this year. My local store now sells the rest for 10 cents each.
