Nicpro3 PCS 1.3 mm Mechanical Pencils Set with 36 Lead Refill, 3 Eraser - Weatherproof Metal Barrel, Heavy Duty Carpenter Pencil for Outdoor Marking Drafting Drawing Sketching Woodworking - with Case

Regarding the this pencil I did by 3 set ( 9 pencils )I do not recommend for any one because there was a small rubber piece which should make the refill stop each push , it’s not work will , I can not fix it , the refill length which each push was not standard I wish they can fix this issue or If they can advice me how I can fix it , its not logical , they depend a lot to make the pencils look nice and heavy duti but its not ! I wish the manufacture department can help me to fix this issue , I done know how to fix this tiny rubber !
