# Replacing a nib ## Overview To buy a replacement nib, you need to find the specific nibs that are compatible with it. You can might find this information: * On the box * Written in the user manual * On the manufacturer's website. It might be listed on a page describing the pen. For this you need to find the model number of your pen. * If you need help, contact support. I recommend your double check your pen against photos of the pen on the manufacturer website. See: * [Finding the model number of your pen](/drawtab/guides/general/finding-pen-model-number.md) * [Finding the model number of your drawing tablet](/drawtab/guides/general/finding-tablet-model-number.md) ## Only use compatible nibs Only put nibs in your pen, that are designed for your pen. I DO NOT recommend putting in nibs from other brands or pens. What sometime happens is that these other nibs fit, but they are not long enough and so they go completely inside the pen and cannot be removed. Meaning, you have to buy a new pen. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
