This dissection tray was a good value for the money. It was sturdy enough such that the students did not cut through the tray while dissecting. If the dissection is not too messy, this tray could be wiped off and used again. I recommend this product.
I bought several of these for a co-op class in which we dissected owl pellets. They were great for laying out the bones before glueing them to the worksheet. They were heavy enough to stay down on the table, and did not have a problem with static at all.
I love these!
I am a huge fan of using these trays with a big group. They make cleanup much easier.
