Lost 'Celebrity Cruises' flask -- reward offered

Hi there, I hope someone can help with this.

My partner lost a rare laser-etched ‘Celebrity Cruises’ flask in a car park in Eastleigh, gifted from her Mum who had her 70th birthday on the ship. It looks very similar to this:

The only difference is the lost bottle carries the Celebrity Cruises logo, along with the X, laser-etched into it. On the bottom is the S’well apostrophe logo. It has been well looked after and doesn’t have a scratch on it.

She left it in a car park in Eastleigh, on top of a ticket machine.

Whilst the flask itself is not of particularly high monetary value, it does carry great sentimental value, and my partner was very upset when she realised she left her gift there.

I’m more than happy to offer a reward for its safe return – this will be greater than the monetary value of the flask itself.

An update to this - the reward still hasn’t been claimed, so I’ll now say I’m happy to offer a reward of up to £1,000. The flask is cheap in nature, but it is very rare and holds a memory of a very important event.

If you know who has it, or have seen it in your travels, please let the person know. The design is very specific, so do not try to photograph a substitute - I will know if it’s the right one!

If you’d like to claim the reward, please provide photographic evidence that you have it, any verify the condition that it’s in. It was completely unscratched.

Many thanks!
