Yea, well before you jump in with both feet... Err arms, I think you should start and learn some basics. Read the list, then try a few things first.
Then, we'll talk about armbinders.
I have one I got years ago. It's a lace up design. But I can't wear it.
No matter what I do or try, both of my arms go numb within 15-20mins.
You can use a string to operate the zipper. However, you should check first, if the opening action works. It is not unlikely, that the upper seam of the glove folds back, when you pull to open. In that case, the direction of the pull is reversed. I think, I explained, how to counteract this in one of my threads about the bolero single glove.
But I found, that most cheapo armbinders are very short, and it only requires a bit of dexterity to pull out one arm, even if it is completely closed and fairly tightly strapped. According to the description, your armbinder is 49 cm long, which is just above my elbows. for me, it should be a matter of seconds to escape - and probably anybody else, who hasn't much shorter forearms.
But even though this toy might not be secure at all, it can still fun for those, who don't look for inescapable bondage (with timer etc.). Until you take it off, your arms will be utterly useless. The next step is a mix of imagination and perhaps something to remind you, how restricted you are (try to eat, for example, or take a shower - don't slip!).
