It's important to consider some things before you begin shopping for a rolling tray. As with any product, not every tray is equal to the others and you may find that you have specific requirements.
Features
A rolling tray may simply be a single sheet on which you can bust down and roll comfortably. However, some trays offer additional features, such as extra areas that can be used to section off weed or slots in place that can hold your rolling papers or filters. Likewise, a tray may have holes drilled into it where you can place your joints or blunts for safekeeping.
Cost
Cost is always a factor when shopping for something. Depending on the features you're interested in, you can find trays that fall into any budget.
Size
The size of the space you'll need in a rolling tray will depend on your specific needs. For instance, if you're seeking an all-around workspace, you'll likely prefer something larger. However, a smaller surface can be sufficient for those who want to be able to easily transport it.
