Yes this would be great gift dude.
I guess she will like and love it since it is personalized and most especially it is engraved with her name.
But if you want this one I can recommend you there is also a Qrypto card where she can also use, easy way transaction too for bitcoin users with multi account of she want. I think she would love it too or she is a bitcoin user, and with the use of her cellular phone.
But the best thing will be giving her your precious time and effort, that thing will melt your girlfriend’s heart as like other girls is looking for their  love ones to do for them.
Anyway good luck dude for your plan, anyway if she truly loves you she will appreciate it.

Cheers.
