Thymine and Adenine

"These are a pair of friendship necklaces made from bead and wire. They are perfect for a best friend or a partner. They are structurally accurate and color coded. They come in a cute bag containing a description of the molecule.

If interested I can ship anywhere else I just need to check the price. If interested just message me and I will look it up."
