[Blindtlk] Identifying Clothes and organization

[Julie J]

Several years ago I saw small, round, plastic pieces with two letter Braille 
abbreviations for various colors and patterns on them.  Each of these 
plastic pieces had a back, sort of like an earring.  So you could press the 
two pieces together with a tag or bit of fabric in between and it would 
stay.

Does anyone know what I'm talking about?  And any idea where I could 
purchase such a thing?  Or do you know of any similar product?  the only 
item I've seen is the metal Braille tags that need to be sewn or pinned into 
garments.

TIA
