Not sure. 金縛る can apparently mean "to be bound or paralyzed", or also "to be tied down by money". What does this item do?
金縛る basically means sleep paralysis. Although it can also mean "tied down by money", the meaning is a little different than being to poor to do anything, but more that one worries about the cost of things to such a ridiculous extent that they are held back. Like not not watching TV because you are too worried about the power bill, or not going out with friends because you don't want to spend money at the bar, on a taxi ect. Although when used in that way, the passive form of the verb is typically used 金に縛られる
1.5x the length of our own products!! (当しゃひ = 当社比)
Technically this is saying that whatever it is that is long (sword maybe?) is 1.5x longer than the second longest sword they have. It sounds a little goofy, something you would expect to see on a TV commercial for some budget department store or something. Like, when someone is trying to sell you a sword, they might tell you how sharp it is, or how it was forged and tempered by some master blacksmith, but with this they are like "Check out this sword its...ahh... longer than our other swords!".
