Elly Warm‑En‑Koud Herbruikbaar Gelpak x3

Bought these after my son fell off his bike and the swelling came up fast. The gel stays soft straight from the freezer so it molds around his knee instead of sitting like a brick, and he actually keeps it on for the full ten minutes now.

My toddler actually asks for the dinosaur one now, which says a lot since he used to scream at the sight of an ice pack. They stay cold long enough for a full bump-and-bruise meltdown, and the gel doesn't get rock hard like the old freezer packs.
