We use a variety of woods: including natural cherry; bubinga; mahogany; curly, burled, and birdseye maple; bloodwood; burled walnut; and many others as we can get them. You may want to simply specify light, medium or dark when ordering and leave it to us to pick what wood is best. <br> <br>Our object chambers are filled with oil and a variety of materials. Generally, if you are ordering a single scope it's a side lite so we use mixed glass for the most spectacular effect. We also do seashells and all dichroic, as well as adding feathers to our mixed glass pieces. You may discuss other options with us if you want a different vision. <br> <br>We have one lighting option: side (meaning the end is blacked out and light should be directed into the side where the clear area is. You hold the scope parallel to the light source. <br> <br>Boxed Sets include 3 different oil-filled chambers; the choices are glass and feathers side lite, mixed glass side lite, dichroic glass side lite, and sea shells side lite. We do them differently sometimes so if you have specific choices on your sets you should let us know, however, artist's choice is usually the best way to go. <br> <br>All Kaleidoscopes are hand made in the USA!!!
