Very nice glasses.  They are a bit smaller than I expected.  The 10.5 oz. ones DO NOT hold 10.5 ounces (even filling it right to the top).  The 5.75 ones do however.  Be SURE to realize that the measurement is with the glass FULL to the top, so if you want it to hold that amount for serving/not spilling- be sure to order one size larger.  Other than that, the glasses fit SO nice in your hand.  The small ones are perfect for little kids.  It's worth the extra money to buy tempered glass.  We have been married for 35 years and have only gone through 2 sets of tempered glasses.  The regular glass ones broke LONG ago. I recommend their purchase.
