I LOVE these dice trays. I've had fabric / neoprene ones in the past and the sides just start to bow, edges fray and poppers can come loose and they generally look tatty. NOT WITH THESE! i have seveal but my mosst long suffering is the lime green (SO BEAUTIFUL) bought many years ago and the UKGE and still going strong. Puts up with lots of folding flat for storage and travel (fit nicely in an A4 folder or box with your chracter sheets and other gubbins) , the sides are lovely an rigid to stop runaway dice (except when you are too enthusiastic!) . I have bought several more since (the design has changed slightly in the years - but not by much but i still trust them to be just as long lived if not more!)
They're the only dice trays i use now
Such a great tray, folds flat for storage, and easy to clean with a clothes brush, no trying to use tape to get into corners of other trays. I have several of these trays, as does the rest of my DnD group.
Get one, and you won't look back!
