Who We Are
Mostlyforgrownups is a UK-based brand founded and operated from Durham, England. We specialise in beautifully crafted crystal-infused glass water bottles and wellness accessories — products designed for adults who appreciate quality, intention, and a little everyday calm.
Trusted Sellers With a Proven Track Record
Before opening this store, we built our reputation selling on eBay for many years — and we're proud to have maintained 100% positive feedback throughout. You can find us there under the username fishingmathsman.
By selling directly through our own store, we're able to offer many of the same great products at better prices — because we don't have to factor in the platform fees charged by auction sites. That saving goes straight to you.
What We Sell
Our core range is crystal-infused glass water bottles, each featuring a genuine crystal insert — including Amethyst, Rose Quartz, Red Jasper, and Tiger's Eye. We also offer a curated selection of drinking glasses, jugs, carafes, and hats and headgear. Every product is chosen with care and quality in mind.
Our Values
We believe in transparency, quality, and honest business. All products are accurately described, fairly priced, and shipped from the United Kingdom. We are committed to providing a straightforward, trustworthy shopping experience.
