I've ordered from them a few times. I got some dragon's breath the last time. prices aren't bad but portions are small (coral frags are also small). I just checked on the macros and the more affordable pieces are approximately 1 inch. I like them and would order from them again. Just know what you're getting.
I also got a nice chunk of dragon's breath on etsy and I recently saw a local reefer selling nice portions of dragon's breath at a very good price so you have options.
I ordered from mosaic and i should receive tomorrow - i was stoked on the shipment - not so much now from the comments haha -- so Steve sells display Macro
