"Well, I haven't tried putting a whole house inside my Arms Band, but other than that, I think you won't have to worry about size." He quips, not really sure how that might help someone who's as adventurous as Senku when it comes to experiments...But it's a limitation, nonetheless. "If it helps, the troll clubs that we collected in Irivar could still make it in mine."

As he speaks, Roland is already in the process of summoning the said material from his own Arms Band. His open palm glows golden and out comes a small backpack, militaristic and made of waterproof nylon fabric. He hands it over to Senku with a small smile on his face, maybe a bit too eager to see his scientific mind assess its feasibility for their blueprints.

"Go crazy." Inside, Senku will find more or less, useful materials: a few meters worth of carbon fiber cable wrapped around itself neatly, and hooks that seem sturdier than steel. A couple of each, but not enough to use for more than one gun.
