SWORKz have introduced new ‘rainbow’ hook and loop straps for E-buggy. Available in Ferrari red and fluorescent yellow, these straps measure 2x27cm and make easy the fix of any Li-Po packs on the S35-3E and on many other E-buggy. The ‘rainbow’ hook and loop straps come in a set of four with two red and two yellow straps.
