No reputable vendor here uses glass anymore for boba.
The screen used was ABS and the .090 thick stuff feels lite but strong. It will far outlast the FG stuff. If you flex the FG just a bit the gelcoat exterior that will be painted will not flex, but crack.
I too wanted it at first, but you'll be better off with RKD or FP or BM. Bobamaker has still not updated his website, but he too has switched over to ABS.
