These are pre-filled replacement pods for the Vuse ePod system, sold two to a pack, so you click one in and swap it when it's empty rather than refilling. Each pod holds 2 mL of e-liquid at 20 mg/mL salt nicotine, the BOLD strength, and is good for up to around 1,000 puffs, so a pack covers roughly 2,000. The pods use Vuse's ceramic heating, which keeps the flavour steady from the first puff to the last, and the design has an easy-view window so you can see the e-liquid level. They fit across the Vuse range, including the ePod, ePod 2 and Pro. The 20 mg strength suits a tight, cigarette-style draw and anyone who wants a fuller hit. If you already vape Vuse, these are the straightforward refill.
