Ceramic Coralline Purple Coral Frag Plugs 100 Pack Free Aquarium Glue for SPS LPS

So far so good, item arrived earlier than expected. Holds glue well and frags steady

I like the ridges and divot on the top.If you 3d print frag racks, 12mm is a good hole size for these. 11 works, but is snug on some of them.Out of a bag of 100, six had the stem snapped off when I got them. One had shattered. They broke in a way that it was easy to tell which stem went to which top and I just glued them back together.I've got a second batch of 100 arriving tomorrow.

Alright I go through plugs often. These get the job done nothing fancy cheap and even come with glue I buy the purple.. colors a little off but not to bad. Couldn’t be happier

Didn't need to be purple

I was weary about purchasing these from the other reviews about not being able to break the stem off. I had no problem breaking off the stem. Look forward to using!
