only 36 euros for this probably 2020s crampons? okay for some more 3-4 years?

Hello everyone! just saw this in my region on marketplace, so wanted to ask if it would be okay for purchasing?

(4th random photo with that black box and info I found by myself when quick-searching on google)

the condition seems ok, however how old are they idk

probably they would go to big mountains with me, since my boots are b2
