Böker Magnum, Balisong Trainer / Bottleopener

Give that bottle cap the business in style! Aside from its stunning appearance, it offers the function and look of a butterfly knife - but without the blade. An eye catcher in the bar, or a gag for your next party! Please note we do not give a guarantee on the screws of the butterfly trainer. Check after training whether the screws are still tight. The trainer may fall when practicing. This can cause the trainer to break. This is also not covered by the warranty. We advise you to tighten the screws with locktite or nail polish before putting them into use
