Whichever size you choose is the size you'll get, in spite of the picture portraying 3 different sizes. That's my fault though, because the description plainly says "3 of same size." I gave it 4 stars because I tried one out last night and it held up to my 100 mph swing with no problem. I'm used to hitting off a 2 3/4" tee though, so I will pull the tee down through my mat a little bit. Again, I got the 3" because I thought I was getting different sizes and was going to experiment on sizes. I got these for my hitting mat that I was using my wooden tees with. The wooden tees last maybe 2 swings, then broke.Eh...if anything else stands out about the tees, I'll update, but be warned, you'll only get 3 of the same size, not a variety. But that is my fault, not the seller's, and not Amazon's. Stay tuned for my review of the "Bionic Glove." Hopefully I ordered that correctly...what a moron...
