Review: De grootte van deze slijpsteen lijkt niet op de omschrijving zoals in de specificaties. Het steentje is ca 7cm x 2,5 cm en 0,5 cm dikte. Dus wanneer je denk een lege envelop te ontvangen blijk deze misschien in toch aanwezig te zijn, goed controleren.
Review: Die Diamant Schleifsteine passen perfekt in den bekannten DMT Schleifen.
