Replacement O-rings

Replacements for a very well insulated bottle

I have had the water bottle for at least 5 years and it is still functioning as good as new, keeping cold liquids still very cold for at least 12 hours. Just lately the O ring has become brittle. And I thought it would be nice to have a spare cap too. I am very happy with the items and how quickly my order was delivered.

Annoyed

I find it ridiculous to pay £3.99 postage for a lightweight plastic item costing £3! Surely you could pack the rings flat in cellophane so they can travel letter post? It’s silly to send the little box out!

Good rings to keep my bottles leak proof.

I use my chilly's bottles most days and replace O rings when needed. I feel confident they won't leak and spoil contents in my bag.
