Compass for mechanical pencils JC-502E This compass can accommodate mechanical pencils, pencils, sign pens, etc. up to 10mm in diameter. The screw for the locking band that completely secures the shaft is missing, so it cannot be completely fixed, but it is still usable. Two regular drafting compasses (photos 7 and 8) One has the (PLUS) stamp. All items are used and have been stored at home. The outer boxes show signs of aging. Please understand the above before purchasing.
