I've used them in the past for some moss, the gamba XII bubble counter and also a pair of long handled trimming scissors.
Service was great and the moss arrived in good condition .... the scissors however were not very good, pretty blunt and didn't give a clean cut. I've still got them, but now only use the took kit I got from aquaessentials and a small pair of bonsai scissors.
However I'd certainly use them again for some of the mosses that I cant find elsewhere.
