Ok!
Ok, but overprized compared to competitors like Bossil (which is great value!).

Idéal pour les poignées de poêles et de casseroles.

Le seul du site envoyé sous blister et pas d'Inde. Je préfère même si c'est deux fois plus cher. Mes écrous d'axe de roues ne se désserent plus. Prévoir la lampe à souder pour le démontage à 300 degrés celsius.
