Or maybe for fruit or wine bottles? Very many on the shoreline this year and last year, not great… #marinelitter #oceanplastic #pollution #whatisthis (forgot hashtags on main post- see there too)

Anyone able to tell me what these are? Last year they were black and scattered over local beaches. This year blue, but again washing up. They’re tubular. Presume washing in from fishing boats, but what for and why? They look new/unused.
(Painted topshells just for show)

Here’s a photo #firstpost of a gem sea anemone (Aulactinia verrucosa) to get things started.
