La Rochere Bees Mug

I ordered one mug just to see it and know what quality it is. The mug is only a 10oz mug, not a 12.3 floz as invoice says it is. I measured with measuring cup 8oz and then added 2 more oz to fill right to the rim. It holds 10 floz and no more. I could be sure of that because I have plain Libby glass mugs that are 12 oz and visibly much larger than this one, so obvious. Company needs to not advertise these as 12 oz mugs. Some people may be very unhappy, I will accept this but will not order more.
