https://www.amazon.com/Foam-Arabic-Cut-Magnetic-Letters/dp/B0CHZ1NVTM (the seller gets the money and not Amazon themselves I think, and I couldn't find it anywhere else ): )

The product has letters cut in foam frames that you can take out the letters and put them back in. I used the frames to sketch the letters individually one by one to spell out عيد مبارك, then I took out Ayn, yeh, dal, Meem, beh, alef, reh, kaf and spelt the word.

Disclaimer, letters are massive by the way. One letter is about the size of a phone. The kaf they used looks a lot like the sindhi squished kaf (ڪ) which makes it even larger.
