How to get more bag storage in Starsand Island

You can increase your bag space by selecting the “Expand” option on your bag and spending the required materials. This process is a bit tricky to figure out the first time around, as there are loads of different tabs and options to choose from in your bag, so here’s a full breakdown of how to get it done.
- Open your bag. The bag icon is located in the upper right corner and can be accessed by clicking on it or pressing the button displayed next to it. On PC, this button is B, but it varies across other platforms. You can also access your bag by selecting the bag icon on your phone.
- Find the “Expand” option. There are lots of tabs and sections in your bag, but the only one you need here is the “Expand” option, which is located in the bottom left corner.
- Spend the required materials. Each bag upgrade has different required materials, with each level up requiring tougher items to unlock. If you don’t have the required resources, you’ll have to get to work gathering them and return to this step once you have what’s needed.
As soon as you spend the required resources, your bag will instantly be upgraded. You can upgrade it at any time, anywhere, even if you’re on the go, as long as you have the materials to do so. As you get to the higher-level bag upgrades, though, you’ll likely need to craft materials, which means you’ll need to find crafters and other machines to get the upgrade resources you’re after.
