3 ممحاة احتياطية لقلم الرصاص الميكانيكي بقطر 3.8 مم

Ordered these as backup for my chalk holder and the 3.8mm fit is spot on, no wobble at all. Three in the blister is handy since I keep one in the case and one at the desk. Erases the chalk lines clean without smudging the board.

Been using the same refill on my chalk pencil for weeks now and it still wipes clean without smearing. Nice that the blister gives you three backups, so I don't have to worry about running out mid-project.

J'ai acheté ces gommes de rechange pour mon porte-mine de 3,8 mm et elles effacent bien les traces de craie sans laisser de résidus. Le lot de trois est pratique, même si j'aurais aimé un emballage plus solide pour le transport.
