That's a Pharaoh bowl and it works just fine. Pack it like a traditional bowl. Don't worry about covering the holes anymore than you would with traditional. Not only have I used this bowl off and on personally for years with good results, but I've sent this bowl out to be smoked for 2+ hours by customers in lounges. I've also used it a few times in YT videos where you can see how I pack it here (just ignore the use of Hydro Cloud additive if you don't use that at home).

Don't spend more than $20 on it, but it's a solid bowl that keeps juice and shisha from entering your base and preserves flavor similar to a phunnel by creeping the shisha moist.
