Clear 1.5ml plastic centrifuge tubes, for putting your scented Q tips in for scentwork. They come pre-drilled with a hole (to allow scent to permeate) . 13mm diameter x 41mm height.
Available in 8 different colours (transparent, purple, orange, blue, pink, red, yellow, brown). This allows you to use a different colour for different scents or to hide on different colour backgrounds.
You can choose to have a magnet glued inside to allow you to stick it on metal surfaces ie on a chair leg, or inside the wheel arch of a car – see photo of one stuck on my fridge door.
Price – 50c each (or $1.50 with magnet inside).
