Ha! I love it. So, is everything as clear as mud to you right now, right? Ask ten different people a question about gloves, and chances are you will get thirteen different answers, and God forbid several of them be lawyers, as you will get a lot more than thirteen answers. One thing is for sure, this is a classic example of why with several exceptions, gloves are highly a matter of personal preference.
The answer is "yes" you can use those gloves for boxing, "if" you want to. Are those gloves the one's best suited for western style boxing? No, they are not. Are long cuff style western boxing gloves with excellent wrist support the one's best suited to muay thai boxing? No, they are not. Are you sure you will only be doing western boxing, or muay thai exclusively?
In the end, a phase commonly used by a Thai bar girl could be the best advice, "up to you." Check out these reviews. I am sure they will help you decide, and be sure to check the "last photo" in the "last review" listed.
