Price is for both. Trays included. The Tasting Bottles have been washed and ready for new tasting solution. There are 8 bottles in total for four different taste profiles: sour, salty, sweet and bitter. The idea is to taste and match. I included some laminated taste labels. The Smelling Jars consists of twelve bottles in all. One set has a black lid and the other has white lid. These still have the old scents in them. We used cotton balls dipped in essential oil for different scents. You may reuse them or put your own scents. The Smelling Jars and Tasting Bottles are sensorial materials in Montessori. Selling together. The trays are made of beechwood/plywood. Trays: tasting: 13”x4”, smelling: 12”x4”
