Individual samples coils featured in prior month's Maker Box subscription box.
Check out more about Maker Box here.
Each sample is approximately 16m long (equivalent of 50g of PLA) and is in a reclosable bag with dessicant.
It is a loose coil, so you may want to print a sample spool or wrap it onto an old spool.
If you are an active Maker Box subscriber, make sure to check the members exclusive discount page (link and password inside your latest box) to get a discount on 2 or more samples.
I love being able to go back and get more samples from boxes past. Being able to try different things without having to risk buying and not liking a full spool is simply wonderful.
