Help needed to identify these 3 matching purple teardrop peices

Hi all,

Can anyone guide me on these pieces I picked up from a house clearance company.

They are small, about 6.5cm round and 5cm high with the handle is 6.5 high.
They are hand made as have all the normal indicators.
The piont is messy and not smoothed or sheered off.
They are all the same colour and they are all one complete colour glass.
The opening is two big for a tapered candle
The shape is similar to a cigar ashtray.

I got a few Czech glass, Sklo union pieces from the same place they they were pressed glass unlike these.

Any help would be great.
