This complex glass screen provides all the function you could wish for with an amazing airflow.
Available in either 14mm or 19mm, both sizes are very popular these days so don't be discouraged if you see a "sold out" notice. That simply means the Octabowl is everything you expect from quality merchandise, as quite a few other people have already discovered. It won't be long until restocking is accomplished, and you can see for yourself why it sells out so often, and that it is more than worth a little extra wait time.
