Perfect for personalised or bags this bag measures 33x44cm and can be sublimation on both sides, alternatively DTF can be used. 
The printable area is recommended at 23x32cm.
Drawstrings are nylon so should either be removed prior to printing or ensure that they are outside of the press area - yes I did forget I had a new larger press and melted them lol
Recommended times and temps are 180c for 2minutes. I used newspaper offcuts inside the bag to prevent the ink bleeding through but if you have a pressing pillow I would recommend that.
