One has signs of being used (slightly scratched), the 3rd is in perfect condition. I believe this one is in fact new. Both are approximately 40.41mm tall, the tip retracts approximately 3.5mm, overall changing the unit to approximately 37.00mm tall.
Unit 2 and 3 are unmarked except for the country of manufacture, Japan. All plastic (tube) packages are marked RBX. I believe all have been previously owned by Windeler EGRG & Consltg/Michigan. Your complete satisfaction is our priority.
