***If you are ordering sticker sheets only, there is $2 shipping (instead of $5 like on all the other products). Make sure to select the “Stickers” shipping option at checkout. If you are ordering stickers + something else, please select the $5 domestic or $15 international option or else your order won’t go through.***

Microalgae are responsible for producing 50% of the oxygen on Earth! We wouldn’t have been able to evolve without them and we wouldn’t be able to breathe without them. This sticker sheet contains 17 of my favorite microalgae (all photos I’ve taken), including diatoms, desmids and euglenas, along with an informational sticker and two stickers with the Couch Microscopy logo. They are high quality vinyl stickers that adhere permanently to surfaces like phones and laptops.
