Is it possible to ship a Nintendo DS game with original packaging as a large letter for 1.45 euro?

I would like to ship a Nintendo DS game. Unfortunately I have no scales at the moment and I do not know how difficult that will be. I would like to ask you for advice. Is this still possible as a large letter for 1.45 euro? Or is there possibly still a cheaper option? I would be very grateful for helpful answers. Stupid comments can be saved please.

Googling helps!

A large letter may weigh up to 500 grams.

I assume that you have a product at home that weighs 500 grams (coffee, rice or similar) and can compare with it.
