2 Premium - Red Single Blade Inflatable Light Saber Swords, Lightsaber, Party, Gift, Action Play, Blow up Darth Vader (Red 1-Blade)

  • Pack of 2 premium inflatable swords. Darth Vader red single blade..
  • New design: Longer, stronger, and better fight action! Great for high-energy low-impact battle..
  • Customize stiffness and impact level by adjusting air pressure. These sabers can be inflated extra-firm to ridged with an air pump, or compressor. They will swell in diameter with over inflation, so try to keep the air pressure at a minimum to achieve the desired firmness, but maintain the original shape..
  • Easy inflation: One-way check valve incorporated in Inlet to help prevent air from escaping while inflating. For best results: Press back of inlet to help establish the seal prior to initial inflation. Inflate, and hold finger over inlet for a few seconds. This gives the check valve time to rest and seal, and helps maintain air between breaths. Close valve, wait a minute or so for the plastic to relax, and inflate further to desired firmness..
  • To deflate: pinch base of valve. This opens valve and allows air to escape..
  • For the perfect air pump, no batteries required, and excellent sanitary choice for inflating these, go with Amazon’s ASIN: B091NDVVP3.
