This is a popular appetizer served in Thai and sometimes Chinese cuisine. It's simply seasoned shrimp wrapped inside a thin sheet of egg roll/spring roll wrapper. It's then fried until crispy and usually served with a side of sweet chili sauce.
Peel the shrimp, keeping the tail on. For each shrimp, turn it over to the bottom side and score about 3 slits about 1/4 of the way into the shrimp, then gently stretch it to make the shrimp straight instead of curvy. Place them in a bowl until all the shrimp are prepped and done. Then add the oyster sauce, garlic powder, and black pepper. Gently mix well and set aside.
Make the flour paste seal by mixing the flour and water together in a small bowl and set aside. This will act as the glue to seal everything together. You can also use one egg to seal them if you prefer.
Prepare the wrappers. If they come frozen, make sure to thaw them first. Cut the wrappers diagonally to create triangles. You should end up with about 50 sheets to work with.
To wrap the shrimp, take a triangle wrapper and place it with the base facing you and the point at the top. Place the marinated shrimp in the center, with the tail sticking out from the base. Take the top point of the wrapper and fold it over the shrimp. Then fold the left side in to cover it. Tuck and roll until you reach the right end tip. Make sure to roll it tightly so the shrimp doesn’t fall out. Seal the end tip with the flour paste. Repeat until all the shrimp and wrappers are used.
Heat a good amount of oil in a pan to 375'F and cook the shrimp for about 5 minutes or so turning for even cooking until golden brown. You will have to cook this in batches as you don't want to overcrowd the pan. Overcrowding will cause the shrimp rolls to get soggy and not cooked correctly. Once golden brown, remove and place into a colander. Repeat until all are fried. Served while it's still crispy with a side of sweet chili sauce OR my favorite: Sriracha tartar sauce.

Notes
Yes, this can freeze them uncooked and fry when ready. Just make sure to freeze them first before bagging them and placing it back into the freezer.
