Engrave bracelet pendant with numbers

Beschreibung des Auftrags

I have several Pandora charms and wanted to engrave them with a date.
Is that possible or are they too small?
It is a matter of 4 pendant. The following engraving should be on it
2/21
5/21
8/21
4/22
So basically just numbers. The font and size don't matter. You should still be able to read it. It doesn't matter where the engraving is made on the pendant. It's just important to me, that the date is written on it somewhere.
Attached are photos of the trailer. However, you don't necessarily see the positions here, where to engrave.
If necessary, I could also send the trailer to you to check, if you can't tell right off the bat, Will the engraving work?.
I like to hear from you.
