Example Input: They do work... mostly. They have held my sheets down from coming off the corners in the night for a few weeks, but it seems like the elasticity has worn off a bit, and it seems that the clamp isn't clamping as well anymore. Especially on one of them. Fortunately, there are 8 included in this pack so I will have to swap it out and see if there is any improvement. Ok otherwise. Update: I'm actually not even using these anymore. They're just more of a hassle to put on than it is to pull the sheet down every night before bed.
Example Output: 3

Example Input: There is no real scent to this was, just a pink color. It did a very good job when I use it but for some reason it did not heat as quickly as many other wax beads I've tried in the past.
